Question 204991: Explain why the line x = 4 is a vertical line.
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! Explain why the line x = 4 is a vertical line.
------------------------------
Plot two points where x = 4 such as (4,2) and (4,6)
------------
Plot those two points and draw a line thru them.
You will see that you get a vertical line.
-------------
Also, if you calculate a slope thru those points
you will get (6-2)/(0) which is undefined. That is
the slope of a vertical line.
