------------------------------------
A. Parallel to 15x+16y=32,
B. Perpendicular to 10x+13y=26
-----------------------------------


slope of A is -15%2F16.

Slope of B is -10%2F13.

slope for line k is %283%2B2%29%2F%28k-5%29, or 5%2F%28k-5%29.


With that, you know about how parallel lines are related, and how perpendicular lines are related; in a plane?
