<PRE><B>Question 1203431</B>
------------------------------------
A. Parallel to 15x+16y=32,
B. Perpendicular to 10x+13y=26
-----------------------------------



slope of A is {{{-15/16}}}.


Slope of B is {{{-10/13}}}.


slope for line k is {{{(3+2)/(k-5)}}}, or  {{{5/(k-5)}}}.



With that, you know about how parallel lines are related, and how perpendicular lines are related; in a plane?</PRE>
