At 7:00 AM there were 14,000 gallons of water in Lance’s pool when he noticed there was a leak. After 6 hours there were only 5,
000 gallons of water remaining in his pool. Write an equation that describes the number of gallons of water as a function of the time the pool has been leaking. y = -5,000x + 14,000
y = -1,500x + 14,000
y = -9,000x + 14,000
Is it possible for a vertical line to have a negative slope?
