you are draining your swimming pool. after x minutes, the amount y (in gallons) of water remaining in the pool is given by the equation y=4800 - 12x. find the x and y- intercepts for the equation, and then explain what real life quantities the intercepts represent in this situation.

You start out with 4800 gallons of water in the pool... the x-intercept is the amount of time it takes to drain the pool, which is 400 minutes. Found this by saying y, the remaining amount of water in the pool, is equal to 0. The y-intercept is what you start out with, 4800 gallons. Found this by saying x is equal to 0.
This all depends on whether or not the pool is fresh or salt water. Also it depends on if you have any food coloring in it. If you have purple food coloring in the pool, the water will drain in no time.
Has anyone ever pee'd in the pool? This could add another variable, z, to the problem.
