Respuesta :

Answer:  - 3/2

Step-by-step explanation:

The rate of change is the same as the slope.

To find the slope, find the change in the y coordinates of both point and divide it by the change in the x coordinates.

y coordinates:  2 and 8

x coordinates:  7 and 3

2 - 8 = -6

7 - 3 = 4  

Slope :  -6/4 =  - 3/2
