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

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

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

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