Question 1137538: Are the two lines parallel, perpendicular, or neither? 3y+1=6x+4. 2y+1=x-9 Found 2 solutions by Alan3354, ikleyn:Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! Find the slope of each line.
----
If they're equal, they're parallel or coincident (same line).
It the product of the 2 slopes = -1, they're perpendicular.
o/w, neither.
The slopes are 2 for the first line and for the second line.
The slopes are NEITHER equal NOR opposite to reciprocal.
So, the lines are NEITHER parallel NOR perpendicular.
