Graphs of Linear Functions help needed.?

Question

An example of an equation for a horizontal line is y = 3, an example of a vertical line is x = -2. Explain how to use a table of values to graph horizontal and vertical lines.

Answer 1

To graph a vertical line, the x coordinate stays the same while the y-coordinate can be anything. Conversely, for a horizontal line, the y-coordinate stays the same and the x can be anything.
