Brent purchased a used vehicle that depreciates under a straight-line method. The initial value of the car is $7500, and the sal
Ilia_Sergeevich [38]
Let the value of the vehicle be described by the equation
V = a + bx
where x =  number of years since purchase
a,b are constants.

When x = 0, V = $7500. Therefore
a + b*0 = 7500
a = 7500

When x = 7, V = $500. Therefore
7500 + 7b = 500
7b = 500 -7500 = -7000
b = -7000/7 = -1000

The equation is
V = 7500 - 1000x

The slope of this equation is the depreciation rate, and it is -$1000 per year.

Answer: $1000 depreciation per year.

kow [346]

Answer:

6

Step-by-step explanation:

The slope is: \frac{y_{2} -y_{1} }{x_{2} -x_{1} }. In this case, for the numerator you get 30. For the denominator you get 5. Divide 30/5 to get 6 as your final slope.

Hope it helps!
