If y = 9x − 7, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs? a) {(0, −7), (1, 2), (−1, −16)} b) {(−7, 0), (2, 1), (−16, −1)} c) {(1, 9), (2, 7), (3, 16)} d) {(7, 9), (8, 10), (9, 11)}

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
