calculate the rate of change <br> -24 ,60) ,( -34, 50<br> please help
VLD [36.1K]

Step-by-step explanation:

the rate of change is the slope of the line connecting both points.

the slope is the ratio y/x indicating how many units y changes, when x changes a certain amount of units when going from one point to another.

so, here

x changes by -10 units (from -24 to -34)

y changes by -10 units (from 60 to 50).

the slope or rate of change is -10/-10 = 1/1 = 1
