It takes 3 minutes to fill an 12-gallon tub with water.  Which equation shows the relationship between the number of gallons of water y and the minutes, x?

12 g / 3min   = 4 gal/min  = rate  (or slope)

 

y = mx + b        b = 0   (the tub starts empty)

y = 4 x              when x = 1    4 gallons

                                  x=2     8 gallons

                                  x=3    y = 12 gallons
