Question 177988
<font size="+2" face="Times New Roman">

Ordered pairs are called ordered because the values are given in a particular order.  If the equation is in x and y, then the ordered pair is (x, y). So where you are given the first number in the ordered pair, you substitute that value for x in the equation and do the indicated arithmetic to determine the value for y that completes the ordered pair.  Where you are given the second number in the ordered pair, substitute that number for y in the equation and do the indicated arithmetic to determine the value for x.
