A bathtub contained 45 gallons of water when the plug was pulled. Six minutes later, 36 gallons of water remained in the tub. Assume the bathtub drained at a constant rate (in gallons per minute). a) Determine the equation of the linear relation (in slope-intercept form) with x = the # of minutes from when the plug was pulled, and y = the # of gallons of water in the bathtub. Sketch the graph. b) What do the slope and the y-intercept of your line indicate? c)Use your equation to determine how much water the bathtub contain 20 minutes after the plug was pulled. d) Use your equation to determine how long after the plug was pulled the bathtub was empty.
