500A new toilet model has two different flush settings
in order to conserve water. One setting uses 1.6 gallons of water per flush and the other setting
uses 0.8 gallons of water per flush. The total amount w (in gallons) of water used in the first setting is given by the equation w = 1.6f where f is the number of times the toilet is flushed. The
total amount of water used in the second setting is given by the equation w = 0.8f. Graph both
equation in the same coordinate plane. What do the slopes and the w-intercepts mean in this
situation?
