Answer:
neither
Explanation:
The equations of two lines are
and

When the slopes of two lines are equal then the lines are parallel.
When the slopes of two lines are negative reciprocal of one another then the lines are perpendicular to each other.
We solve for y and check the slope of two equations
(subtract x on both sides)

Now divide by -3 on both sides

Slope of this line is


Slope of second line is 3
Slopes of both lines are not negative reciprocal of one another
So they are neither
