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?

A discrete graph, labeled "New Car Gas Mileage". The x axis is Gas Used in gallons, scaled in ones. The y axis is Distance in miles, scaled in increments of 25. The points are: (2, comma 65), and (4, comma 135).

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