Solve.
-The average value of a certain type of automobile was $\$ 13,740$ in 1993 and depreciated to $\$ 7080$ in 1997 . Let $y$ be the average value of the automobile in the year $x$ , where $x = 0$ represents 1993 . Write a linear equation that models the value of the automobile in terms of the year $x$ .

A) $y = - 1665 x + 13,740$
B) $y = - 1665 x + 7080$
C) $y = - 1665 x + 420$
D) $y = - \frac { 1 } { 1665 } x - 7080$
