You can put this solution on YOUR website! Determine if these points are parallel, perpendicular, or neither. 3x-4y=2 and 4x-3y=3
--------------------
Those are not points, they're equations of straight lines.
----
Solve for y:
3x-4y=2
y = (3/4)x - 1/2
Slope m = 3/4
-------------
4x-3y=3
y = (4/3)x - 1
m = 4/3
============
Equal slopes --> parallel
Inverse negative reciprocal slopes --> perpendicular
=======
3/4 & 4/3 are reciprocals, but not negative --> neither
