What is the average rate of change from x = - 1 to x = 2?

The average rate of change between - 1 and 2 is 1.

Step-by-step explanation:

To get this, use the two ordered pairs (-1, 5) and (2, 8). Now use the slope formula to find the rate of change.

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

m = (8 - 5) / (2 - - 1)

m = 3/3

m = 1
