Vertical and Horizontal Lines

The video tutorial explains how to write equations for vertical and horizontal lines passing through a given point. It emphasizes the simplicity of these equations and provides a method to remember which is which by graphing the points. The tutorial demonstrates that vertical lines have constant x-values, while horizontal lines have constant y-values, and provides examples to illustrate these concepts.
