Final answer:
The rate of change between the points (-1, -3) and (3, 5) is 2.
Step-by-step explanation:
To find the rate of change between two points, we can use the formula:
rate of change = (change in y) / (change in x)
Using the given points, (-1, -3) and (3, 5), the change in y is 5 - (-3) = 8 and the change in x is 3 - (-1) = 4.
Therefore, the rate of change between the points is 8/4 = 2.
