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.
m1=3
m2=-1
Parallel lines have identical slopes.
Perpendicular lines have slopes that are negative reciprocals of each other.
m1%2Am2=-1
Since neither of these applies, the lines are neither parallel nor perpendicular.
