Answer 1

Answer:

Slope is equal to the change in y over the change in x , or rise over run.

m=change in y/ change in x

The change in x is equal to the difference in x-coordinates (also called run), and the change  in y is equal to the difference in y-coordinates (also called rise).

m=y2−y1/x2−x1

Substitute in the values of x and y into the equation to find the slope.

m=0−(2)/9−(5)

Simplify.

m=−12

Answer 2

Answer: (7, 1)

Midpoint formula = ([tex]\frac{x1 , x2}{2}[/tex] , [tex]\frac{y1, y2}{2}[/tex])

5 + 9 / 2 = 7

2 + 0 / 2 = 1
