he price for gasoline is represented by the equation y 5 2.72x, where y represents the total price for x gallons of gasoline. Determine whether each statement describes the graph of the equation. Choose True or False for each statement. a. Fifteen gallons of gasoline can be represented by the u Tr ue u False coordinates (15, 40.8). b. The graph goes through (5.44, 2) and (8.16, 3). u Tr ue u False c. The slope represents gasoline being sold at a rate of u Tr ue u False $2.72 for each gallon. d. If the price of gasoline decreases $0.03 per gallon, u Tr ue u False then the slope would be 2.75.
