) A water tank is emptying steadily by 2 liters of water per hour. There were 2 liters of water 6 hours after

midnight. Let x represent the number of hours since midnight, and let y represent the number of liters of water
in the tank. Find the equation showing the amount of water at time x

1 answer

y(6) = 2, so

y = -2(x-6)+2 = 14-2x
for 0 <= x <= 7
