Solve. Assume the exercise describes a linear relationship. When writing a linear equation, write the equation in slope-intercept form.The average value of a certain type of automobile was $15,960 in 1991 and depreciated to $5340 in 1995. Let y be the average value of the automobile in the year x, where x = 0 represents 1991. Write a linear equation that models the value of the automobile in terms of the year x.
A. y = - 
x - 5340
B. y = -2655x + 5340
C. y = -2655x + 15,960
D. y = -2655x - 5280
