Solve Two Variable Inequalities

Solving two variable inequalities involves graphing a line and shading a portion of the graph that identifies the solution region.  So before you proceed make sure you really know how to graph a line (linear equation).  Next when graphing a line make sure you pay attention to the inequality symbol- this will determine if the line is dashed or solid. Let me add that when you need to figure out what side of the line to shade test the point (0, 0) into the inequality then determine if the statement is true or false.  If the result of plugging in (0, 0) produces a true statement shade towards (0, 0) if the statement is false shade away from (0, 0)….good luck!





some key topics that involve solving two variable inequalities:

* system of inequalities
* linear programming
* quadratic inequalities
* more complex college prep math
