for the line slope on the bottom two answers are -4/3 and -3/4
There are 2 pictures.
1. (x,y)=(-1,5),(0,2),(1,-1),(2,-4). Option -3 is correct.
2. The slope of the line is 4/3. Option-1 is correct.
Given that,
There are 2 pictures.
In the first picture we have to find which table satisfy the equation.
In the second picture we have to find slope of the given graph.
First,
The given equation is y=-3x+2
In every option the x values are same that is -1,0,1,2.
Substitute x value as -1,0,1,2
Taking x as-1
y=-3(-1)+2
y=3+2
y=5
Taking x as 0
y=-3(0)+2
y=2
Taking x as 1
y=-3(1)+2
y=-3+2
y=-1
Taking x as 2
y=-3(2)+2
y=-6+2
y=-4
Therefore, we got (x,y)=(-1,5),(0,2),(1,-1),(2,-4). Option -3 is correct.
Now, We see the second picture.
Given line point are (2,2) and (-1,-2)
Slope of the line formula is [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
Slope =(-2-2)/(-1-2)
Slope=-4/-3
Slope=4/3
Therefore, the slope of the line is 4/3. Option-1 is correct.

what is QR????????????????????????????????
The length QR of the similar triangles given is; QR = 34
How to solve similar triangles?
Similar triangles are defined as triangles that have the same shape, but then their sizes may differ. What this means is that all equilateral triangles and even squares of any side lengths are examples of similar objects.
Now, from the given image we see showing the triangles, we can see that line RS is parallel to line QT. This means that we can use the concept of ratio of similar triangles to generate the unknown length QR.
Thus;
QR/(QR + QU) = ST/(US)
Thus;
QR/(17 + QR) = 42/63
QR/(17 + QR) = 2/3
3QR = 34 + 2QR
3QR - 2QR = 34
QR = 34

The midpoint of AB is M(3,-2). If the coordinates of A are (8, 4), what are the
coordinates of B?
The coordinate of B is (2,-8).
What is coordinate geometry?A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
A midpoint is a point that lies on a line connecting two other locations and is in the middle of the line. Given that the midpoint of AB is M(3,-2) and the coordinates of A are (8, 4).
The midpoint will be calculated by using the formula below:-
[tex]\frac{8+x}{2}[/tex] = 3
8 + x = 6
x = -8 + 6 = -2
x = -2
Similarly for y
[tex]\frac{4+y}{2}[/tex] = -2
4 + y = -4
y = -8
Hence, The coordinates of the point B will be (-2,-8).

For a project in her Geometry class, Chloe uses a mirror on the ground to measure the height of her school’s flagpole. She walks a distance of 8.85 meters from the flagpole, then places a mirror on flat on the ground, marked with an X at the center. She then steps 1.1 meters to the other side of the mirror, until she can see the top of the flagpole clearly marked in the X. Her partner measures the distance from her eyes to the ground to be 1.15 meters. How tall is the flagpole? Round your answer to the nearest hundredth of a meter.
The height of the flagpole will be 9.25 m to the nearest hundredth of a meter.
What is geometry?It is defined as the branch of mathematics that is concerned with the size, shape, and orientation of two-dimensional figures.
Given that, after moving a mirror with an X in the middle to a level position on the ground 8.85 metres away from the flagpole.
The top of the flagpole is then plainly indicated in the X as she moves 1.1 metres to the opposite side of the mirror. Her companion calculates that there are 1.15 metres between her eyes and the ground.
From the similarity of two triangle,
1.15 / h = 1.1 / 8.85
1.1 h = 1.15 × 8.85
1.1 h = 10.1775
h = 9.25 m
Thus, the height of the flagpole will be 9.25 m to the nearest hundredth of a meter.

A polynomial function has zeros at -2, 0, and 10 (all multiplicty of 1). Write a function in standard form that could represent this function.
The standard form is p(x) = x³ - 8x² - 20x
What is polynomial function?
A polynomial function is a function such as a quadratic, a cubic, a quadratic, and so on, involving only non-negative integer powers of x.
Given, A polynomial function has zeros at -2, 0, and 10.
The factors in 'x' will be, (x+2) (x - 0) and (x - 10)
Now, multiply the factors if we want the polynomial from zeros
p(x) = (x+2) (x-0) (x-10)
p(x) = (x²+2x) (x - 10)
p(x) = x³ - 10x² + 2x² - 20x
p(x) = x³ - 8x² - 20x

If the rectangle is 24 inches long and 13 inches wide and given that 1 inch is equal to 2.54 centimeters, the rectangle's area is 2012.9 sq cm.
What is a rectangle?The two-dimensional geometry is described as having 90-degree angles between consecutive sides. It is a specific kind of quadrilateral. the area that a rectangle takes up in two-dimensional planning geometry.
The following formula can be used to determine a rectangle's area:
Rectangle area = length x width
It is given that, the dimensions of a rectangle are 24 inches long by 13 inches wide.
If 2.54 centimeters equal one inch, The following unit conversion is obtained as,
1 inch = 2.54 centimeters
L = 24 inches = 24 × 2.54 = 60.96 cm
W = 13 inches = 13 × 2.54 = 33.02 cm
The area of the rectangle is,
A = L × W
A= 60.96 × 33.02
A=2012.9 cm²
Thus, if a rectangle has a length of 24 inches and a width of 13 inches, the area of the rectangle will be 2012.9 sq cm.

The coordinate of the intercepts of the graph are (0, -1) and (1/3, 0).
What is termed as the coordinate intercepts?An intercept is a y-axis point whereby the slope of a line passes. It is the y-coordinate of a point on the y-axis in which a straight line or a curve intersects. This is represented by the equation for a straight line, y = mx+c, where m is the slope and c is really the y-intercept.There are two types of intercepts: x-intercept and y-intercept. The x-intercept is the point in which the line crosses the x-axis, and the y-intercept is the point in which the line crosses the y-axis.The equation of the line is given as;
y = 3x - 1.
For x-intercept put y = 0;
0 = 3x - 1.
x = 1/3
x-intercept = (1/3, 0)
Now, for y-intercept, put x = 0.
y = 3x0 - 1
