(04.01 MC) If y = 8x − 2, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs? (1 point) {(−1, −1), (3, 15), (−4, 0)} {(7, 35), (4, 17), (2, 10)} {(2, 5), (8, 50), (9, 66)} {(−2, −18), (2, 14), (0, −2)} 4. (04.01 MC) A watering can dispenses water at a rate of 0.15 gallon per minute. The original volume of water in the can was 5 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 point) {(1, 5.0), (2, 4.85), (3, 4.60)} {(5.0, 1), (4.85, 2), (4.70, 3)} {(1, 4.85), (2, 4.70), (3, 4.55)} {(4.85, 1), (4.70, 2), (4.45, 3)} 5. (04.02 LC) The graph represents function 1 and the equation represents function 2: A graph with numbers 0 to 4 on the x-axis and y-axis at increments of 1. A horizontal straight line is drawn joining the ordered pairs 0, 3 and 4, 3. Function 2 y = 6x + 1 How much more is the rate of change of function 2 than the rate of change of function 1?
