The rate of change of the following data is A. 4

How to solve

We can calculate the rate of change using the slope formula:

Rate of change = (y2 - y1) / (x2 - x1)

Using the first two data points:

Rate of change = (5 - (-7)) / (2 - (-1)) = 12 / 3 = 4

Using the second two data points:

Rate of change = (25 - 5) / (7 - 2) = 20 / 5 = 4

Using the last two data points:

Rate of change = (37 - 25) / (10 - 7) = 12 / 3 = 4

Since all calculations yield the same result, the rate of change for the data is 4.

Therefore, the answer is A) 4.
