Graphing Systems of Inequalities

The video tutorial covers graphing systems of inequalities, starting with a recap of linear equations and inequalities. It explains the concept of systems, where multiple graphs are on the same axes, and how solutions are found in the double-shaded region. An example is provided, demonstrating how to graph two inequalities, highlighting the importance of line types and shading directions.

What does a system of inequalities involve?

• One graph on a set of axes

• More than one graph on the same set of axes

• A single inequality

• A single equation
