Question

What is the average rate of change of y with respect to x over the interval [-2, 6] for the function y = 5x + 2?

Answer 1

Answer:

5

Step-by-step explanation:

Average rate of change is slope, which is change in y over change in x:

$\frac{[5(6)+2]-[5(-2)+2]}{6-(-2)} =\frac{32-(-8)}{8} =5$
