Solve Assume the Exercise Describes a Linear Relationship $\$ 19,500$ In 2007 and Depreciated To

Multiple Choice

Solve. Assume the exercise describes a linear relationship.
-The average value of a certain type of automobile was $\$ 19,500$ in 2007 and depreciated to $\$ 13,200$ in 2012. Let $y$ be the average value of the automobile in the year $x$ , where $x = 0$ represents 2007 . Write a linear equation that models the value of the automobile in terms of the year $x$ .

A) $y = - 1260 x + 19,500$
B) $y = - \frac { 1 } { 1260 } x - 13200$
C) $y = - 1260 x + 13,200$
D) $y = - 1260 x + 6900$
