One way of finding the solution set of a system of linear inequalities in two variables is by graphing.

To graph a system of linear inequalities and see its solution set, first graph the corresponding system of linear equations. While graphing these equations, use either solid or dashed lines: use solid lines for “is greater than or equal to” (≥) or “is less than or equal to” (≤) inequalities, and dashed lines for “is greater than” (>) or “is less than” (
