Understanding Vertical and Horizontal Lines

This video tutorial explores the concepts of vertical and horizontal lines on a graph. It explains that vertical lines have an undefined slope and are represented by equations like x = some number, while horizontal lines have a slope of zero and are represented by equations like y = some number. The video also covers the equations of the x-axis and y-axis, and provides examples to illustrate the calculation of slopes for vertical and horizontal lines.
