<PRE><B>Question 975773</B>
y = mx + b
y is the total value
m is the appreciation (goes up) or depreciation (goes down)
x is the number of years
b is the initial purchase price


y = mx + 2000 {the initial purchase price is 2000}


m would be negative, because as the number of years increases after the initial price, the total value of the car would depreciate (decrease)
