1. Interpreting Graphs: We often use graphs of recent data to project the changes in future data. The following is the graph of a car’s value. The car was bought for $20,000. Each year, the car’s value decreases $2,800. We can use this to project what the worth of the car will be if we ever decide to sell it. a. Write a formula to model the car’s value, where “y” is the value of the car and “x” is the number of years. b. Find the value of the car algebraically after five years. Does this match the graph above?
