The value of a car decreases (depreciates) immediately after it is purchased. The value of a car you recently purchased can be modeled by the symbolic rule V(x) = -1350x + 18,500, where V(x) is the market value (in dollars) and x is the length of time you own your car (in years). a. Explain how you know that the graph of this relationship is a line. Determine the slope of this line. What is the practical meaning of slope in this situation? b. Determine the vertical intercept. What is the practical meaning of this intercept? c. Determine and interpret the value V(3).
