Graphing 6 - Horizontal and Vertical Lines
This lesson focuses on graphing horizontal and vertical lines in the form x=k or y=k, where k is a number. The video demonstrates how to plot three ordered pairs with one variable fixed and the other variable varying, and how to connect these points to form a line. The lesson also highlights that x=k is a vertical line passing through (k,0), while y=k is a horizontal line passing through (0,k). The video encourages viewers to avoid memorization and instead rely on plotting ordered pairs to graph lines.
Covers the special cases of graphing horizontal and vertical lines which are in the form x=k or y=k, where k is any number. This is part 6 of a series of videos about graphing lines.

This video explains the process of making tables and graphing horizontal and vertical lines. Because these are special cases in which there is only one variable, they can be a bit tricky if you haven't seen them. This is a great tutorial on graphing these lines.
