1) Note that perpendicular lines have reciprocal and opposite slopes, parallel lines share the same slope, and neither does not follow any of these
[tex]\begin{gathered} y=2x+4,\Rightarrow m=2 \\ y=-2x+3,\Rightarrow m=-2 \end{gathered}[/tex]
2) Note that these slopes are neither perpendicular nor parallel. So the answer is:
[tex]c)Neither[/tex]
