Answer :
Parallel is same slope.
Perpendicular is same slope but you have make it opposite and flip it.
For example if your slope is 2/3. For Perpendicular it would be - 3/2.

There's no such thing as parallel or perpendicular "to a point". A problem like that
will always want the new line to be parallel or perpendicular to another line.
-- If the new line is parallel to the given line, then they have the same slope.
-- If the new line is perpendicular to the the given line, then the slope of the
new line is [ 1 / slope of the given line ].
In either case, you now have the slope of the new line and a point on it.
From there, you should have no trouble finding its equation.
