Verifying Graphs of Systems of Inequalities

This video tutorial teaches how to verify the accuracy of graphed systems of inequalities by using points from different regions of the graph. It explains how to determine if the correct half-plane is shaded and addresses common misconceptions, such as the belief that only the intersection of lines needs checking. The tutorial provides a step-by-step guide to graphing a system of inequalities, shading regions, and verifying solutions by checking points in various regions. It concludes with methods to ensure graph accuracy, emphasizing the importance of verifying points that satisfy both or only one inequality.
