\n" ); document.write( "\n" ); document.write( "The reason they call it an \"ordered pair\" is because the two elements are always in the same order, namely

. That means that the first value is ALWAYS the independent variable value, and the second value is ALWAYS the dependent variable value. So replace the

in your equation with the first value of the ordered pair, then replace the

in your equation with the second value in your ordered pair. Do the indicated arithmetic. If you end up with a true statement, then the point is an element of the solution set of the equation. If you end up with a false statement, then the point is NOT an element of the solution set of the equation.\r
