Exploring Horizontal and Vertical Lines

The video tutorial covers the concepts of horizontal and vertical lines, focusing on their slopes and equations. It explains that horizontal lines have a slope of zero, while vertical lines have an undefined slope. The tutorial provides examples of calculating slopes and writing equations for both types of lines. It also introduces the acronyms HOY and VUX to help remember the characteristics of horizontal and vertical lines, respectively. The video concludes with graphing exercises to reinforce the understanding of these concepts.
