Step-by-step explanation:
graph the line through (1,0) with m=0
The equation of the line passing through the point (1,0) with slope 0 is
y = 0
The line passing through the point (1,0)
The slope of the given line is m = 0
So, let us write the equation of the line using slope-point form
y = mx + b
where m is the slope
(x,y) is the point passing by the line
b is the intercept
So , now let us substitute the known values in the above equation
0 = 0(1) + b
b = 0
Therefore , the intercept of the given line is b = 0.
Thus , the equation of the line can be written as
y = mx + b
where m = 0 and b = 0
y = 0x + 0
y = 0
Therefore , the equation of the given is y = 0 which is a origin

What is a Triangle?Having three straight sides and three angles, a triangle is a flat figure.In Euclidean space, the total of a triangle's internal angles is always 180 degrees. The parallel postulate of Euclid is comparable to this fact. By using the measurements of the first two angles, it is possible to calculate the size of the third angle in any triangle. An angle that is a linear pair (and thus supplementary) to an interior angle is the outside angle of a triangle. The exterior angle theorem states that the measures of two inner angles that are not contiguous to each other add up to the measure of an exterior angle of a triangle. Any triangle's three outside angles, one for each vertex, add up to a total of 360 degrees.To learn more about Triangles, refer to:

The slope of the table is 3.
In this question, we have been given a table.
We need to find the slope of the table.
For aby two points (x1, y1) and (x2, y2), we use the formula of slope,
m = (y2 - y1) / (x2 - x1)
m1 = (15 - 30) / (-5 - 0)
m1 = (-15) / (-5)
m1 = 3
For a pair of points (-5, 15) and (10, 60)
m2 = (60 - 15) / (10 + 5)
m2 = 45 / 15
m2 = 3
For a pair of points (10, 60) and (5, 45)
m3 = (45 - 60) / (5 - 10)
m3 = -15 / -5

write the new coordinates after the triangle is rotated 180 degrees counterclockwise about the origin.
For the new coordinates of point A, that is A' = (x', y'), we have:
x' = 2 . cos (180º) = 2 . (-1) = -2
y' = 10 . cos (180º) = -10
The same happens to the other points. So, for B we have :
x' = 3 . (-1) = -3
y' = -4 . (-1) = 4

The required equation is x+4y-9 = 0.
What is an equation?
Algebra is concerned with two types of equations: polynomial equations and the particular case of linear equations. Polynomial equations have the form P(x) = 0, where P is a polynomial, while linear equations have the form ax + b = 0, where a and b are parameters, when there is only one variable. To solve equations from either family, algorithmic or geometric approaches derived from linear algebra or mathematical analysis are used. Algebra also investigates Diophantine equations with integer coefficients and solutions. The approaches employed are unique and derive from number theory. In general, these equations are complex; one frequently searches just for the existence or lack of a solution, and, if they exist, the number of solutions.
The equation is formed below
(y-2) = {(1-2)/(3+1)} (x+1)
or, y-2 = - 1/4 (x+1)
or, 4(y-2) = -1(x+1)
or, 4y - 8 = 1 - x
or, x+4y-9 = 0

a) El coste total es directamente proporcional al número de estudiantes.
b) Existe una relación directa entre el coste total y el número de estudiantes al existir una constante de proporcionalidad.
c) La constante de proporcionalidad tiene un valor de 15 y representa el precio de ingreso de cada estudiante al zoológico.
d) El coste total por 120 estudiantes es $ 1,800. 95 estudiantes cuestan $ 1,425.
Cómo analizar relaciones de proporcionalidad directa entre dos variables
a) Sea y el coste total pagado para una excursión en el zoológico de la ciudad, en pesos, y x el número de estudiantes que visita el zoológico. Existe una relación directa entre las dos variables si la siguiente expresión es satisfecha:
y = k · x
Donde k es la constante de proporcionalidad, en pesos por estudiante.
A continuación, comprobamos si la relación de proporcionalidad directa existe:
Año 2.010
k₁ = 1260 / 84
k₁ = 15
Año 2.011
k₂ = 1050 / 70
k₂ = 15
Año 2.012
k₃ = 1395 / 93
k₃ = 15
Puesto que k₁ = k₂ = k₃, el coste total es directamente proporcional al número de estudiantes.
b) Existe un relación de proporcionalidad directa debido a la existencia una única constante de proporcionalidad.
c) La constante de proporcionalidad es igual a 15 y representa el costo por estudiante.
d) Si sabemos que y = 15 · x y x = 120, entonces el coste total es:
y = 15 · 120
y = 1800
El coste total es de $ 1,800.
Ahora, si sabemos que y = 15 · x, y = 1,425, entonces el número de estudiantes que ingresan es:
1,425 = 15 · x
x = 1,425 / 15
x = 95
95 estudiantes tienen un coste total de $ 1,425.

(e) The area of triangle H is 4/9 times the area of triangle G.
(f) The area of triangle B is 9/16 times the area of triangle H.
(a) Triangle G and Triangle F
Consider triangle F,
The height of the triangle is 8.
The base of the triangle is 6.
The hypotenuse of the triangle is 10.
Area of ΔF = ( 1/2 ) × b × h = ( 1/2 ) × 6 × 8 = 24 square units.
Consider triangle G,
The height of the triangle is 4.
The base of the triangle is 3.
The hypotenuse of the triangle is 5.
Area of ΔG = ( 1/2 ) × b × h = ( 1/2 ) × 3 × 4 = 6 square units.
Therefore,
Area of ΔF = 4 × Area of ΔG
(b) Triangle G and Triangle B
Consider triangle G,
The area of the triangle is:
Area of ΔG = ( 1/2 ) × b × h = ( 1/2 ) × 3 × 4 = 6 square units.
Consider triangle B,
The height of the triangle is 2.
The base of the triangle is 3/2.
The hypotenuse of the triangle is 5/2.
Area of ΔB = ( 1/2 ) × b × h = ( 1/2 ) × 3/2 × 2 = 3/2 square units.
Now, 4 × 3/2 = 6
Therefore,
Area of ΔG = 4 × Area of ΔB
Area of ΔB = 1/4 × Area of ΔG
(c) Triangle B and Triangle F
Consider triangle B,
Area of ΔB = ( 1/2 ) × b × h = ( 1/2 ) × 3/2 × 2 = 3/2 square units.
Consider triangle F,
Area of ΔF = ( 1/2 ) × b × h = ( 1/2 ) × 6 × 8 = 24 square units.
Now, 16 × 3/2 = 24
Therefore,
Area of ΔF = 16 × Area of ΔB
(d) Triangle F and Triangle H
Consider triangle F,
Area of ΔF = ( 1/2 ) × b × h = ( 1/2 ) × 6 × 8 = 24 square units.
Consider triangle H,
The height of the triangle is 8/3.
The base of the triangle is 2.
The hypotenuse of the triangle is 10/3.
Area of ΔH = ( 1/2 ) × b × h = ( 1/2 ) × 2 × 8/3 = 8/3 square units.
Now, 9 × 8/3 = 24
Therefore,
Area of ΔF = 9 × Area of ΔH
Area of ΔH = 1/9 × Area of ΔF
(e) Triangle G and Triangle H
Consider triangle G,
Area of ΔG = ( 1/2 ) × b × h = ( 1/2 ) × 3 × 4 = 6 square units
Consider triangle H,
Area of ΔH = ( 1/2 ) × b × h = ( 1/2 ) × 2 × 8/3 = 8/3 square units.
Now,
9/4 × 8/3 = 6
Therefore,
Area of ΔG = 9/4 × Area of ΔH
Area of ΔH = 4/9 × Area of ΔG
(f) Triangle H and Triangle B
Consider triangle H,
Area of ΔH = ( 1/2 ) × b × h = ( 1/2 ) × 2 × 8/3 = 8/3 square units
Consider triangle B,
Area of ΔB = ( 1/2 ) × b × h = ( 1/2 ) × 3/2 × 2 = 3/2 square units
Now,
16/9 × 3/2 = 8/3
Therefore,
Area of ΔH = 16/9 × Area of ΔB
Area of ΔB = 9/16 × Area of ΔH

number of miles a man should walk and jog in order to burn at least 500

The required linear equation is 100x + 140 y = 500.
What is a linear equation?If an equation is written in the form ax + by + c=0, where a, b, and c are real integers and the coefficients of x and y, i.e., a and b, respectively, are not equal to zero, then it is said to be a linear equation in two variables. Examples of two-variable linear equations are 10x+4y = 3 and -x+5y = 2.
Therefore, a linear equation in two variables is any equation that can be written in the form ax + by + c = 0, where a, b, and c are real values, and a and b are not equal to zero. This implies that you can come up with a ton of these equations. Solution: It is possible to write 2x + 3y = 4.37 as 2x + 3y - 4.37 = 0.

To find the length of the shortest side of the triangle.
Now, According to the question:
We know that
Area of triangle is = 1/2 x base x height
Put the values of base and height in above formula
27.5 = 1/2 × (x + 4) × (x - 2)
27.5 × 2 = x (x - 2) + 4(x -2 )

Define BODMAS
BODMAS is an acronym to remember the order of mathematical operations – the correct order in which to solve maths problems. Bodmas stands for
B-Brackets,
O-Orders (powers/indices or roots),
D-Division,
M-Multiplication,
A-Addition,
S-Subtraction.
Solve the given expression,
(-2.678) + 4.5 + (-0.68)
Follow the Bodmas rule, to solve the given expression.
First, open the brackets,
-2.678 + 4.5 - 0.68
Now, put together -ve terms
-2.678 - 0.68 + 4.5
Add the -ve terms, we get
-3.358 + 4.5
Now subtract this, we get
1.142 or 1.1 (round to nearest tenth)
Hence, the nearest tenth is option(B.) i.e, 1.1 and actual sum is option(C.) i.e, 1.142
