You can put this solution on YOUR website!
The parallel line will have slope 1.
The perpendicular line will have slope -1.

You can set up each solution starting with either point-slope form equation or from slope-intercept equation. Point-slope form may be easiest.

(A)
y-0=1%28x-%28-1%29%29
highlight%28y=x%2B1%29

You can do #B.
