The graph below displays gas mileage for a new car.    

  1. Use the graph to predict the number of miles the car could travel with three gallons of gas.

    A line drawn through the two points would cross 3 at about 100 miles, so that is a reasonable estimate.

  2. Use the graph to predict the number of miles the car could travel with five gallons of gas.

    Where does the line from part (a) cross 5 gallons?

Use the eTool to continue graphing points by adding point to the table.
