Solve. Assume the exercise describes a linear relationship.The average value of a certain type of automobile was $19,920 in 2007 and depreciated to $14,340 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 = -1116x + 14,340
B. y = - x - 14340
C. y = -1116x + 8760
D. y = -1116x + 19,920
