You can stay completely in slope-intercept form if you want to.

which you can reform as for whatever reference point with those coordinates you have.

Find the equation of the line that is perpendicular to this line and passes through the point (5,-2)
This needs m=, which is negative reciprocal of the slope in your given equation. That makes the line you want PERPENDICULAR.
, which you just need to simplify.

Find the equation of the line that is parallel to this line and passes through the point (5,-2)
The slope here will be ; do this one on your own.
