Find the average rate of change for the given function x=-1 to x=2

a. 4/3
b. -4/3
c. -3/4
d. 3/4

The Average rate of change (the slope) is -4/3

Step-by-step explanation:

Find two Exact point like point A (-1,4) and point B (2,0)

Then count how many spaces does point A have to move left to right and down to get to point B.

since it moves down the number will be negative.

You will have to go 3 spaces to the right and 4 spaces down.

therefore giving you a slope of -4/3

b. astronomers
