Question

What is the rate of change of (2, 15.50) and (4, 31)?

a) 7.75
b) 8.25
c) 15.75
d) 16.50

Answer 1

The rate of change between the points (2, 15.50) and (4, 31) is 7.75.

Step-by-step explanation:

To find the rate of change, or slope, between two points, we use the formula:

slope = (change in y) / (change in x)

Given the points (2, 15.50) and (4, 31), we can calculate the slope as follows:

slope = (31 - 15.50) / (4 - 2)

slope = 15.50 / 2

slope = 7.75

Therefore, the rate of change of the given points is 7.75.
