## Inequalities in 2 variables[edit]

Linear inequalities in 2 variables are typically in the form of , where *m* is the slope of the line and *b* is the y-intercept.

Graphing an inequality is easy. First, graph the inequality as if it were an equation. If the sign is ≤ or ≥, graph a normal line. If it is > or <, then use a dotted or dashed line. Then, shade either above or below the line, depending on if y is greater or less than mx + b.
