Zachary purchased a new car for $21,995. The value of the car linearly depreciated to $9,100 over 10 years. Write a linear equation to represent the value y of Zachary's car (in dollars) after x years since its purchase.

y(x) = 21995 - 12895.5x

Step-by-step explanation:

The value of the car after x years is given by the following linear function:

In which y(0) is the initial value and a is how much it depreciates per year.

Zachary purchased a new car for $21,995. The value of the car linearly depreciated to $9,100 over 10 years.

This means that

So

So

y(x) = 21995 - 12895.5x

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,
