Parallel lines have slopes that are identical.
m%5B1%5D=m%5B2%5D
Perpendicular line have slopes that are negative reciprocals.
m%5B1%5D%2Am%5B2%5D=-1

3x%2By=0
y=-3x
m%5B1%5D=-3
Parallel, m%5B2%5D=-3
Perpendicular, m%5B2%5D=1%2F3
.

.
x=0
Slope is undefined.
Parallel, slope is undefined.
Perpendicular, m%5B2%5D=0.
