You are comparing two printers to buy for college. The first printer from JW Computers prints six pages a minute and the second from Siller Printers prints four and a half pages per minute. You estimate that your average paper is 18 pages long. If you were to print an 18 page paper from each printer use the dots as endpoints for two functions of pages left of the 18 page report with respect to time. Use the blue for JW Computers and green for Siller printers.

Once you have successfully graphed the functions, write them in function notation. Use J(t) for JW Computers Printer and S(t) for Siller Printers.
