Question

find rate of change
-3, 2.5
0, 1
2, 0

Answer 1

To find the rate of change, we need to calculate the slope of the line passing through the given points.

The formula for calculating the slope of a line passing through two points (x1, y1) and (x2, y2) is:

m = (y2 - y1) / (x2 - x1)

For the first set of points (-3, 2.5) and (0, 1):
m = (1 - 2.5) / (0 - (-3))
m = -1.5 / 3
m = -0.5

So, the rate of change for these points is -0.5.

For the second set of points (0, 1) and (2, 0):
m = (0 - 1) / (2 - 0)
m = -1 / 2
m = -0.5

So, the rate of change for these points is also -0.5.
