4. The Daytona 500 is a NASCAR event that requires drivers to complete 200 grueling laps around a track. Each lap is 2.5 miles. One particular NASCAR driver drove the first 65 laps of the race at a constant speed. The next 65 laps the driver increased their average speed 10mph. For the remaining 70 laps the NASCAR driver increased their average speed an additional 3mph. The driver's total driving time (not including pit stops, etc.) was 2.5 hours. Determine the drivers speed during each stage. Use the table below to help you answer this question /5 Distance (mi) Speed (mph) Time (h) Stage 1: First 65 Laps Stage 2: Next 65 Laps Stage 3: Last 70 Laps

Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
