Horizontal & Vertical Lines

This video tutorial explains the equations of vertical, horizontal, and diagonal lines. It begins with a brief introduction to the axes and the video content. The tutorial then covers vertical lines, where all points share the same X coordinate, and horizontal lines, where all points share the same Y coordinate. It further explains diagonal lines, focusing on y = x and y = -x, where the coordinates have specific relationships. The video concludes by summarizing how to find the equations for these types of lines.
