Plot the given point B(3,5) and a vertical line through it:


Next draw several possibilities for A(x,3), for instance
A(-4,3), A(-1,3), A(1,3), and A(5,3)

 

Draw a line through them:

  

Now you can see that the only value of x is the value where the
blue line crosses the green vertical line, which is at A(3,3)

The line is vertical if all the x-values of
every point it passes through is the same.
so that means it goes through ( 3, 30274 )
and also ( 3, -905 ), so it must also go
through ( 3,3 ), so
