Answer:

-5/3

Explanation:

m=(y2-y1)/(x2-x1)

m=(-8-7)/(5-(-4))

m=-15/(5+4)

m=-15/9

m=-5/3

Answer:

C

Explanation:

The formula to find the slope of a line is:

(y2 - y1) / (x2 - x1)

We can substitute the points (-4, 7) and (5, -8) to find the slope:

(-8 - 7) / (5 - (-4))

(-15) / (5 + 4)

(-15) / 9

This can be simplified to

- 5 / 3

which is option C
