To graph inequalities, first, begin by rewriting the inequality in slope-intercept form (y = mx + b) if necessary. Next, graph the corresponding equation as if it were an equality, using a solid line for ≤ or ≥ and a dashed line for < or >. Then, determine which side of the line to shade by testing a point not on the line (usually the origin) to see if it satisfies the inequality. Finally, shade the appropriate region to represent all solutions of the inequality.
