Question

How do you find the average rate of change of `y=3x-2` over [0,5]?

Answer 1

The average rate of change is 3

Explanation:

The average rate of change is the change in y over the change in x or `(Delta y)/(Delta x)` or `(y_2-y_2)/(x_2-x_2)`

In this problem the equation is linear, so the rate of change is the slope of the line, namely `3`.
