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.

What is the equation of the vertical line where all points have an X coordinate of 3?

What is the equation of the horizontal line where all points have a Y coordinate of 6?

What is the equation of the diagonal line where the X and Y coordinates are always the same?

What is the equation of the diagonal line where the coordinates are not the same, specifically when X is -2 and Y is 2?

From the video, what types of lines can you find the equations for?
