Walter pays $4 for each gallon, g, of gas for his

lawn mower. He uses a gift card worth $5 to

reduce the amount he owes for his purchase.

How much money, m, will Walter owe if he buys

4 gallons of gas? Make a table using 2, 3, and 4

as values for g. Graph the ordered pairs, and then

write an equation to solve the problem.
