This video tutorial covers the process of graphing solutions to systems of linear inequalities. It begins with an introduction to the concept and outlines the steps involved in graphing these systems. The tutorial includes multiple examples, demonstrating how to graph and shade regions for different types of inequalities, including those with dashed and solid lines. The video emphasizes identifying the double-shaded region as the solution and provides tips for using test points to determine shading. The tutorial concludes with a summary of the key points covered.
