Is each line parallel, perpendicular, or neither parallel nor perpendicular to a line whose slope is −6?
Parallel, slope is the same, perpendicular slope is opposite and reciprocal
so
line n, with slope −6 , same slope -----> Parallel
line p, with slope 1/6 , opposite and reciprocal -----> Perpendicular
line q, with slope −1/6 , -----> Neither
line m, with slope 6, -----> Neither
