Question 48353: Are the following lines parallel, perpendicular, or neither?
L1 through (-4,-7) and (1,3)
L2 through (2,6) and (4,10) Answer by Nate(3500) (Show Source):
You can put this solution on YOUR website! M = (y2 - y1)/(x2 - x1) = (3 + 7)/(1 + 4) = 10/5 = 2
M = (y2 - y1)/(x2 - x1) = (10 - 6)/(4 - 2) = 4/2 = 2
The lines are parallel.
