Lesson Summary:

In this lesson, Julie Harland teaches us how to graph linear inequalities with two variables. She demonstrates with two examples and explains when to use a dotted or solid line. She reminds us to pick an ordered pair on the line to ensure we shade the correct side. As always, visit to view more math lessons organized by topic.
