Solution to a Linear Inequality in Two Variables
An ordered pair is a solution to a linear inequality in two variables if substituting the coordinate values for the variables produces a true mathematical statement. Just as single-variable inequalities (such as ) are satisfied by infinitely many numbers, a linear inequality in two variables is generally satisfied by infinitely many ordered pairs. To formally verify whether a given ordered pair is a solution, you must substitute its specific and values directly into the inequality and evaluate whether the resulting numerical statement holds true.
