Graphing Linear Inequalities
Learning Objective
I can graph linear inequalities on the coordinate plane and identify the solution set.
Key Concepts
When graphing inequalities, a dotted line is used for < or >, while a solid line is used for ≤ or ≥.
To determine which side of the line to shade, you can test a point like (0, 0) in the inequality; if the point makes the inequality true, shade that side.
If an inequality only has one variable (e.g., x < 2), the graph will be a vertical or horizontal line, depending on the variable.
