Question

Find the Average Rate of Change between the points given below.

(3, -7) and (5, 20)

Your answer:​

Answer 1

Answer:
13.5

Step-by-step explanation:
The equation to find the slope (another word for the rate of change) of the line is (y2-y1)/(x2-x1) when the given points are (x1,y1) and (x2,y2).

When we plug in the given points, (3,-7) and (5,20) we can start solving.

(y2-y1)/(x2-x1)
(20-(-7))/(5-3)
Two negatives make a positive
= (20+7)/(5-3)
= 27/2
= 13.5

I hope this helps!
