8. 2X(X-10)(X+10)
i am not sure if no. 8 is right
The answer is D:10 cm, I just took it and got this.
Answer:
Slope = 2 Y-Intercept = (0, 3)
Step-by-step explanation:
Slope : 
which is 
from two points: point1 (x1 , y1) and point2 (x2, y2).
For the purpose of getting the slope I will be using point (0, 3) as point 1
and point (-3, -3) as point 2.
If you plug in 0 as x1, 3 as y2, -3 for x2, and -3 for y2:
= 
= 2
Y-Intercept: The y intercept is the point where the line is touching the y axis. Which in this graph, there is only point (0,3).
Step-by-step explanation:
To find the slope intercept form of any equation using two points, you first need to find the slope. You can do this using the slope formula below.
m(slope) = (y2 - y1)/(x2 - x1)
In this equation, we find the slope by putting in the values we have given the points. The first point you have would be (x1, y1). So if your first point is (3, 1), you would put 3 in for x1 and 1 in for y1. Then you do the same for the second point using (x2, y2).
After you've solved that equation and got m, you can use point-slope form. Take your first point and your newly found slope and plug the values into the following equation.
y - y1 = m(x - x1)
After this, you can solve for y and that will be your slope intercept form.
