5.6 Graphing Inequalities With Two Variables
Megan Tompkins
Guided Notes
Key concepts students will learn:
- •
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.
