Graph a linear inequality when the boundary lies on the y axis

The video tutorial explains how to graph the linear inequality x ≤ 0. It begins with an introduction to the coordinate system, highlighting the x and y axes and the origin. The tutorial then demonstrates how to graph the line x = 0, which is the y-axis, and explains the shading required for x ≤ 0. It also covers the importance of determining whether the line should be solid or dashed. Finally, the tutorial shows how to test points to identify the true region of the inequality, concluding with a practical example.

What does the equation y equals 0 represent in the context of graphing linear inequalities?

Explain the process of determining which side of the line to shade when graphing the inequality.
