Answer by josmiceli(19441) (Show Source): You can put this solution on YOUR website!
A line is perpendicular to another line if their slopes are related this way:

where means slope of the line(s)
It is given that a line has the equation
You usually find by comparing the given equation
with the general equation , but what
you have is more like where ,
so must be zero.
What is ?

= infinity, or a vertical slope.
So, you have a vertical line that goes through (2,4).
All vertical lines have the form
From (2,4), I see that the line is
