Question

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

Answer 1

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
