How to graph the system of linear inequalities of one horizontal and one vertical

The video tutorial explains how to graph a system of two linear inequalities. It begins with setting up the coordinate system and creating tables of values for each inequality. The tutorial then demonstrates how to plot points and draw vertical and horizontal lines, distinguishing between dashed and solid lines based on inequality symbols. Finally, it covers how to determine the shading of the solution region using test points.

What does it mean if a boundary line is not included in the solution of an inequality?

Describe the process of shading the correct region when graphing a system of inequalities.
