What do I need to know to graph a system of linear inequalities

This video tutorial explains how to graph linear inequalities by first understanding how to graph linear equations. It covers the importance of shading and using test points to determine solution areas, as well as how to decide if lines should be dashed or solid based on the inequality. The tutorial also emphasizes identifying solutions on the graph and using test points to verify them.

Explain the difference between dashed and solid lines in the context of linear inequalities.
