Give three ordered pairs from the table x y 2 -5 -1 7 3 -9 5 -17 6 -21

Anytime you want to make an ordered pair, the x comes first, followed by the y. The format is (x, y). You can pick any x you want but the y must match the x. In the table, if you take x = 2, you have to take its matching y of y = -5. Repeat this left to right matching for as many pairs as you want.

Thus three ordered pairs are (2, -5) and (-1, 7) and (3, -9).

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

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