Graphing a system of linear inequalities that are parallel and shading the feasible region

The video tutorial explains how to graph systems of inequalities using different methods. It begins with an introduction to graphing inequalities and then demonstrates the intercept method for graphing lines. The tutorial covers plotting points, determining line types, and choosing test points for shading. It also includes graphing a second inequality and analyzing the results. The video concludes with a summary of the process for graphing systems of linear inequalities.

How do you determine the shading for the graph of an inequality?

What is the significance of the test point (0,0) in the context of graphing inequalities?

Explain the relationship between the slopes of parallel lines in the context of inequalities.
