You can use to find the slope of a line going through and .
I like to line up the points and subtract vertically. Then put 2nd difference over 1st difference.
(6,h)
minus
(7,-10)
------------
-1 h-(-10)
This also said to be equal to -7:
Multiply -1 on both sides:
Subtract 10 on both sides:
[texh=-3[/tex]
So if h=-3 then the slope of the line going through (6,h) and (7,-10) is -7.
Let's test it:
(6,-3)
minus
(7,-10)
----------
-1 7
So the slope is 7/-1=-7. This is the intended goal.

What is BODMAS?
BODMAS, often known as the order of operations, is a method for carrying out operations in an arithmetic expression. Math is all about logic and some established principles that facilitate our computations. BODMAS is one of those commonly used rules for consolidating expressions with multiple operators.
Solution Explained:
A/Q, The price of one toy is $12
The cost of setting up the shop is $50
Therefore, the amount Emilio earns after selling 35 toys is:
(12 X 35) - 50
= 420 - 50
= 370
Hence, Emilio earns $370

11. Using the equation: y + 2 = 3(x - 1).
a) Identify the slope and y-intercept.
b) Graph the equation.
c) Does the point (0,0) satisfy the equation?
Justify your answer.
For the given equation, the slope is 3 and the y-intercept is -5. From the graph, it is possible to see that the point (0,0) does not satisfy the equation.
Linear Function
An equation can be represented by a linear function. The standard form for the linear equation is: y= mx+b , for example, y=x+19. A line equation also can be represented by the point-slope form: [tex](y-y_1)=m(x-x_1)[/tex].
m= the slope.
[tex](x_1,y_1)[/tex]= the coordinate of a point.
For the given example: m=1 and b=19.
The question gives: y + 2 = 3(x - 1). Therefore,
y + 2 = 3(x - 1)
y=3x-3-2
y=3x-5
Letter A - Identify the slope and y-interceptIf y=3x-5 . Here, you have a standard form of a linear equation y=mx+b. Where:
m= the slope. It can be calculated for Δy/Δx.
b= the constant term that represents the y-intercept
Thus, the slope is 3 and the y-intercept is -5.
Letter B - Graph the equation.For this, you should do a table with points
x y= 3x-5
-2 y=3*(-2)-5=-6-5= -11
-1 y=3*(-1)-5=-3-5= -8
0 y=3*(0)-5=0-5= -5
1 y=3*(1)-5=3-5= -2
2 y=3*(2)-5=6-5= 1
Draw a graph from these points, see the attached image.
Letter C - Does the point (0,0) satisfy the equation?The point (0,0) does not satisfy the equation because when x=0 because y is different than zero (0). See below.
y= 3x-5, for x=0
y=3*0-5

What are fractions?A fraction is a number that has a numerator as well as a denominator.
1 / 2 is an example of a fraction. The top part of the fraction is the numerator and the bottom part of the fraction is the denominator.
Fractions represent one value. Dividing the numerator by the denominator shows what decimal value fractions have. For example, 1/2 is equal to 1 ÷ 2 which equals 0.5.

Can anyone write the equation of the graph?
The equation of the absolute value graph is f(x) = |x - 3| + 5
How to determine the equation of the graph?The graph represents the given parameter
From the graph, we can see that the graph is an absolute value graph
An absolute value graph is represented as
f(x) = a|x - h| + k
Where h and k are the vertex of the graph
In this case, they are
h = 3 and k = 5
This is because the minimum point of the graph is (3, 5)
Substitute values for h and k in the form of the equation
So, we have the following representation
f(x) = a|x - 3| + 5
A point on the graph is (2, 6)
This gives
a|2 - 3| + 5 = 6
When the value of variable a is solved, we have
a = 1
So, the equation becomes
f(x) = 1 * |x - 3| + 5
Evaluate the products
f(x) = |x - 3| + 5
Hence, the equation of the graph is f(x) = |x - 3| + 5

The flag of a country contains an isosceles triangle. (Recall that an isosceles triangle contains two angles with the same measure.) If the measure of the third angle of the triangle is 45° more than three times the measure of either of the other two angles, find the measure of each angle of the triangle. (Recall that the sum of the measures of the angles of a triangle is 180°.)
The measure of each angle of this isosceles triangle is equal to 27°, 27°, and 126°.
What is an isosceles triangle?An isosceles triangle can be defined as a type of triangle that has two (2) of its sides equal in length and two (2) equal angles. This ultimately implies that, an isosceles triangle comprises two (2) angles that have the same measure or are equal in magnitude.
Let the variable x represent the angles that have the same measure or are equal in magnitude. Therefore, the sum of the measures of the angles of this isosceles triangle is given by this mathematical expression:
x + x + (45° + 3x) = 180°.
5x + 45° = 180°.
5x = 180° - 45°
5x = 135°
x = 135°/5
x = 27°
Therefore, the measure of each angle of the isosceles triangle is given by:
First angle = 27°.
Second angle = 27°.
Third angle = 45° + 3(27) = 126°.

On Sunday she ran 3 miles on the treadmill and completed 1 mile in the elliptical, and burned 505 calories. Write and solve a linear system to find the number of calories Reese burns on the machine
Answer:The equations are 5t + e = 725 and 3t + e = 505
Step-by-step explanation:Subtract equation (2) from equation (1) and you arrive at;
2t = 220
Divide both sides of the equation by 2
t = 110
Having calculated the value of t, substitute for the value of t into equation (1)
5t + e = 725
5(110) + e = 725
550 + e = 725
Subtract 550 from both sides of the equation
e = 175

Since it is labeled that this triangle has two equal sides, it is isosceles. Isosceles triangles' acute angles are always congruent, so we can infer that there are two angles with a measurement of 29 degrees. Knowing that all of the angles in a triangle add up to 180 degrees, we can set up this equation:
2*29 + 11x - 65 = 180
58 + 11x - 65 = 180
-7 + 11x = 180
11x = 187
x = 17
Knowing that "x = 17" we can find the measurement of the obtuse angle:
11*17 - 65
= 187 - 65

What is x-intercept and y-intercept
The x-intercept is where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis. Thinking about intercepts helps us graph linear equations.
First, find x-intercept
For x-intercept it means y = 0
observe the graph and see the blue line cuts the x-axis when y = 0
We see, x = -250
so, the x-intercept is = (-250, 0)
Now, same thing do to find y-intercept
For y-intercept it means x = 0
observe the graph and see the blue line cuts the y-axis when x = 0
