6. Enrico is filling his pool. The pool has 3,000 gallons of water in it now. The water hose that Enrico uses puts 500 gallons per hour into the pool. Write an equation for the number of gallons y of water in the pool after x hours. Identify the slope and the y-intercept.
The slope is 500 because it is gaining 500 gallons of water every hour. The y-intercept is 3,000 because the pool started off with 3,000 gallons in it.
