Find the average rate of change.

x values: 0, 9, 13, 14
y values: 100, 52, 29, 7

To find the average rate of change, we need to calculate the change in y-values and divide by the change in x-values.

The change in y-values is the difference between the final y-value and the initial y-value, which is 7 - 100 = -93.

The change in x-values is the difference between the final x-value and the initial x-value, which is 14 - 0 = 14.

Therefore, the average rate of change is -93/14 = -6.64.
