The video tutorial explains how to graph linear inequalities in two variables. It covers the use of boundary lines, either dotted or solid, depending on the inequality type. The tutorial demonstrates using test points to determine which side of the boundary line to shade, indicating the solution region. Several examples are provided, illustrating different types of inequalities and graphing techniques.

What type of line is used to graph a strict inequality?

• Curved line

• Solid line

• Dotted line

• No line
