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


1.  Replace *[tex \Large x] in the equation with the value in the *[tex \Large x]-coordinate of the given ordered pair.


2.  Replace *[tex \Large y] in the equation with the value in the *[tex \Large y]-coordinate of the given ordered pair.


3.  Perform all indicated arithmetic.


4.  If the result is a true statement, such as *[tex \Large 5\ =\ 5], then the given ordered pair is an element of the solution set of the equation.  But if, after you have done all of the arithmetic, you get an absurd result, such as *[tex \Large 3\ =\ 8], then the given ordered pair is not an element of the solution set of the equation.
