A watering can dispenses water at a rate of 0.35 gallon per minute. The original volume of water in the can was 9 gallons. Which set of ordered pairs shows the volume of water in the can in gallons (y) as a function of time in minutes (x) from the first minute after the can starts dispensing water?

{ (1, 9.0), (2, 8.65), (3, 8.30) }

{ (9.0, 1), (8.65, 2), (8.30, 3) }

{ (8.65, 1), (8.30, 2), (7.95, 3) }

{ (1, 8.65), (2, 8.30), (3, 7.95) }
