At the beginning of each semester, students at the University of Minnesota receive one prepaid copy card
that allows them to print from the copiers and printers on campus. The amount of money remaining on the
card can be modeled by a linear equation where A represents how much remains on the card (in dollars)
and p represents the number of pages that the student has printed. The graph of this linear equation is
given below.
