You are draining your fish aquarium . after 2 minutes there are 6 gallons of water in the aquarium. after 5 minutes the aquarium is empty . write an equation that represents the volume y(in gallons) of water in the aquarium after x minutes

Graph the line that represents a proportional relationship between d and t with the property that an increase of 33 units in t corresponds to an increase of 44 units in d. what is the unit rate of change of dd with respect to t? (that is, a change of 11 unit in t will correspond to a change of how many units in d? )
