CCGPS CA 4.2.2 Example 1

Andrew wants to estimate his gas mileage, or miles traveled per gallon of gas used. He records the number of gallons of gas he purchased and the total miles he traveled with that gas. Create a scatter plot showing the relationship between gallons of gas and miles driven. Which function is a better estimate for the function that relates gallons to miles: [math]y = 10x[/math] or [math]y = 22x[/math]? How is the equation of the function related to his gas mileage?
