find an equation that goes through (4,0) and (4,4)
-----------------
slope = [4-0]/[4-4] = 4/0
This indicates the graph has an infinite or undefined slope; it is a vertical line.
---------------------
Since it passes through two points where x=4 it will pass through all the points
where x=4.
EQUATION:
x=4

Plot the two points 

 

Draw a straight line through those two points:




It's vertical so that means that every point
on the graph has its x-coordinate as 4. So
the equation is just simply:

    x = 4

That's all there is to the equation of a 
vertical line.
