Final answer:
The rate of change between the points (5,17.25) and (7,15.25) is 1.
Step-by-step explanation:
To find the rate of change between two points, divide the change in the y-values by the change in the x-values. In this case, we have the points (5,17.25) and (7,15.25).
The change in y-values is 17.25 - 15.25 = 2, and the change in x-values is 7 - 5 = 2. Therefore, the rate of change is 2/2 = 1.
