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.

2y= 3 2 x−2 y = − 1 3 x + 1 y=− 3 1 x+1

y=2x−1 5x−4y=1 is (1,1)(1,1) a solution of the system?

The price for gasoline is represented by the equation y=3.69x, where y represents the total price for x gallons of gasoline. on a graph, the number of gallons is represented on the horizontal axis, and the total price is represented on the vertical axis. determine whether each statement describes the graph of the equation. select true or false for each statement
