No.
They're neither.
The slope of the 1st is +3
The slope of the 2nd is -1
--------------
Parallel lines have the same slope.
Perpendicular lines have negative inverse slopes.

Neither.

Parallel lines have identical slopes.
Perpendicular lines have slopes that are negative reciprocals of each other.

Since neither of these applies, the lines are neither parallel nor perpendicular.
