    we have the two points (-2,8) and (2,0)

    the average rate of change from x = -2 to x = 2 is the same as the slope through those two points

    use this slope formula \[\Large m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\]

    the slope of the line through (-2,8) and (2,0) is -2 so the average rate of change is -2
