Anna purchased a new car for $25,000. The car will decrease in value 15% each year. The value of Anna's car is modeled on the graph by function f where x is the time in years after Anna purchases her car.

Aline passes through the point (–7, 5) and has a slope of 1/2 which is another point that the line passes through?

What adds to be the bottom number but also multiplies to be the top number with 8 on the bottom and 15 on top

In order for the function to be linear, what must m be and why? m = 22 because the rate of change is 1. m = 20 because the rate of change is 3. m = 22 because the rate of change is -1. m = 20 because the rate of change is -3.
