Rewrite the inequality in slope-intercept form if possible
Graph the boundary line by replacing the inequality sign with an equals sign
Use a solid line for ≤ or ≥
Use a dashed line for < or >
Choose a test point not on the line
Substitute the test point into the inequality
Shade the side of the line that makes the inequality true
For one-variable inequalities, graph the solution on a number line
Use an open circle for < or >
Use a closed circle for ≤ or ≥
Shade left for less than or less than or equal to
Shade right for greater than or greater than or equal to
