Learn how to graph a system of three linear inequalities ex 14

The video tutorial explains how to graph a system of three linear inequalities. It covers the process of graphing each inequality separately, identifying slopes and intercepts, and determining whether boundary lines are solid or dashed. The tutorial also demonstrates how to test solutions using a test point and how to shade the regions that satisfy all inequalities, ultimately identifying the solution region for the system.

What does it mean if a boundary line is dashed in the context of linear inequalities?
