Is each line parallel, perpendicular, or neither parallel nor perpendicular to a line whose slope is - 3/4?

line m, with slope 3/4

line n, with slope 4/3

line p, with slope - 4/3

line q, with slope - 3/4

Parlalle means has same slope

perpendicular means the slopes multiply to get - 1

line q has slope of - 3/4 same as other so it is paralell

-3/4 times 4/3=-1

line n is perpendicular

lines m and p are nether

q is paralell

n is perpendicular

m and p are neither
