You can put this solution on YOUR website! Are the following lines parallel, perpendicular, or neither? L1 through (9, 2) and (3, –8) L2 through (–3, 5) and (5, –1)
------------
Slope of L1 = [2--8]/[9-3]=10/6=5/3
Slope of L2 = [-1-5]/[5--3]= -6/8=-3/4
-------------
L1 and L2 are not parallel or perpendicular.
