Answer:
Neither.
Step-by-step explanation:
Parallel lines have equivalent slopes while perpendicular lines have opposite reciprocal slopes. (Opposite meaning different signs and reciprocal meaning flipped fraction)
[tex]wx:~m=\frac{4-3}{6-(-3)}\\wx:~m=\frac{1}{9}\\\\yz:~m=\frac{-6-(-4)}{8-6}\\yz:~m=\frac{-2}{2}\\yz:~m=-1[/tex]
These lines are neither parallel nor perpendicular.
