I just wanted to say; You are awesome! My Son came home with this homework and he didn't know how to do this. I was sooo frustrated that he didn't pay attention in class. This video really helped us. So Thank you. Thank you very much! :)

so all x values are vertical and all y are horizontal?

@503JAYr Typically the other way around. X is usually horizontal and Y vertical.

which way does the line go if its undefined?

I think you are asking about the slope. The slope of a vertical line is said to be "undefined", so if the slope is "undefined", then it is a vertical line.
Sometimes a vertical line is said to have a slope of infinity, which also makes sense.
If the slope is zero, then it is a horizontal line.
