A Boeing 747 starts out a long flight with about 57,260 gallons of fuel in its tank. The airplane uses an average of 5 gallons of fuel per mile. Write an equation that models the amount of fuel remaining in the tank over the course of the flight. Graph the equation using a graphing calculator, and then draw the resulting graph on graph paper.

Read the problem statement and then reread the problem, determining the known quantities.

Identify the slope and the y-intercept.

Graph the equation on your calculator.

Draw the resulting graph on graph paper.
