How do you write an equation in point slope form that passes through P(-3,-2) and perpendicular to y=3?
It is not possible to write an equation for the perpendicular line in point-slope form.
It is possible to write it in the form
In general, if a line has slope
The slope is the multiplier of
It is possible to construct an equation for a perpendicular line by following these steps:
(2) Reverse the sign of the term in
The combination of these two geometrical operations is equivalent to rotating by a right angle.
