Vertical and Horizontal Lines Concepts

The video tutorial explains the concepts of horizontal and vertical lines using the acronyms HOY and VOX. HOY is used for horizontal lines, where the slope is zero, and the equation is in the form y = b. VOX is used for vertical lines, where the slope is undefined, and the equation is in the form x = a. The tutorial provides examples of how to write equations for both types of lines based on their intercepts.
