Question 54646: given line1 passing through the points (-4,-1) and (-1,0) and line2 passing through the points (5,8) and (0,4) are the lines parallel, perpendicular, or neigher? Answer by tutorcecilia(2152) (Show Source):
You can put this solution on YOUR website! Lines that are parallel have the same slope.
Lines that are perpendicular have slopes that are negative reciprocals of each other.
.
Line #1 = m=(0-(-1))/-1-(-4) [plug the values into the formula for a slope]
m=1/3
.
Line # 2 =m=(4-8)/0-5)=-4/-5=4/5
.
Looking at the slopes of both lines, the lines are neither parallel nor perpendicular.
