    a baby pool that held 120 gallons of water is draining at a rate of 6 gal/min. the function f(x) = 120 -6x gives the amount of water in the pool after x minutes. Graph the function and find its intercepts. what does each intercept represent?

    The Y intercept would be the amount you started with (120) and the X intercept would be the number of minutes until there are 0 gallons left (20 I believe)

    This is about the easiest math problem ever. OK take some graph paper and draw a straight line from the Y axis (vertical) value 120 to the X axis (horizontal) value 20. The Y intercept represents volume and the X axis (as always) represents the time.

    Some of the points passed through are:
    (0,120)
    (1,114)
    (2,108)
    (3,102)
    (4,96)
    (5,90)
    You get this by plugging in a value of x.
    The y intercept represents how much water is left.
    The x intercept represents the number of gallons.

    y = 120g when x = 0

    Is the amount of water (120g) in the full pool, in minute 0

    Where y = 0, x = 20m.

    When x = 20m, the amount of water in the pool is 0.
