Question

The graph models the value of an automobile over a 7 year period of time.

Which equation best represents the relationship between x, the age of the automobile in years, and y, the value of the automobile in dollars​

Answer 1

Y = mx + c

C = 22,000

But slope is unknown

Y= mx + 22000

Answer 2

y=-500x+22,000

Explanation:

It's this one because the 22,000 shows the initial value of the automobile and -500x is how much value the automobile loses per year.
