7-68.

The graph below displays gas mileage for a new car. 7-68 HW eTool (Desmos) Homework Help ✎

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.

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.
