Question

Ms. Armstrong purchased a car for $20,000. After 4 years, the car was only worth $8,000. Write an equation in slope intercept form that can be used to find the value of the car y, after x number of years.

Answer 1

$20,000=4x

Explanation:

First if we want to find out how much the price of the car went down we would have to find out how much the price went down by subtracting $20,000 by $8,000. I got 12,000. Then we have to find out how much the price went down every year. So, $12,000 ÷ 4 = $3,000. So, in 4 years the price went down $3,000 dollars every year
