The value of a car decreases at a constant rate. after 3 years the value of the car is 15,000. after 2 more years, the value of the car is 11,000 write and solve a linear equation to find what fahrenheit temperature this is.

The linear equation is : y = -2000·x + 21000

Step-by-step explanation:

Let the time be denoted by x and the value of the car be denoted by y

After 3 years the value is 15000

So, point is (3,15000)

After 2 years the value is 11000

So, point is (5,11000)

Now, to find the linear equation we need to find the slope(m) of these two obtained points : (3,15000) and (5,11000)

So, the required linear equation will be :

y  -15000 = -2000·(x - 3)

⇒ y - 15000 = -2000·x + 6000

⇒ y = -2000·x + 21000
