Question 888388
<font face="Times New Roman" size="+2">


Your question makes no sense whatsoever.  You ask if a particular ordered pair is a solution of some set of (presumably) two-variable inequalities, but you don't provide any inequalities.  Then you provide a single variable equation.


In general, to determine if a particular ordered pair is an element of the solution set of a two-variable inequality, substitute the x-coordinate of the ordered pair in place of the x-variable in the inequality, then substitute the y-coordinate of the ordered pair in place of the y-variable.  Do the indicated arithmetic.


If the result is a true statement, then the ordered pair IS an element of the solution set. Otherwise, not.
