Question

Find the rate of change between:
(-4,1/2)
(1,-1)

Need help!!!

Answer 1

The rate of change between two points is the difference in the y-coordinates divided by the difference in the x-coordinates.

Let's call the first point (-4, 1/2) Point 1, and the second point (1, -1) Point 2.

The difference in the y-coordinates is:

-1 - 1/2 = -3/2

The difference in the x-coordinates is:

1 - (-4) = 1 + 4 = 5

So, the rate of change between the two points is:

(-3/2) / 5 = -3/10

Therefore, the rate of change between Point 1 and Point 2 is -3/10.
