Determining if Lines are Parallel, Perpendicular or Neither

Determine if the following pairs of lines parallel, perpendicular or neither. L1 = line 1, L2 = line 2

L1 through (-3,-2) and (1,3) and L2 through (0,3) and (4,8)

L1 with equation x + 2y = 6 and L2 through (0,3) and (9,0)

...lope of line L2 = (8 - 3)/(4 - 0) = 5/4

Since the slopes of both the lines are equal, therefore L1 and L2 are parallel.

Answer: Parallel

L1 with equation x + 2y = 6 and L2 through (0,3) and (9,0)

We can write ...
