How to find the rate of change using coordinate pairs 3,5 and 7,25

The rate of change is 5/1 or 5

Step-by-step explanation:

(3,5) and (7,25)

The rate of change is the same as finding the slope between two points

To find the slope you use this formula

(Y1-y2)/(X1-X2)

Y1=5 Y2+25

x1=3 X2=7

(5-25)/(3-7)

-20/-4

5/1

5
