y = ax + b

If "a" of two lines are equal, they are parallel

If "a" of two lines are the opposite inverse, they are perpendicular

As we have:

y = 3x + 2

y = -3x - 1

To be parallel both need to be 3, they aren't

To be perpendicular one of them should have a being the opposite inverse

Opposite inverse of 3 = -1/3

So they aren't perpendicular too.

Option neither.
