You don&#39;t have a math problem, you have a reading problem.  Go back and look at the instructions for posting on this site.  If you don&#39;t understand the instruction:  &quot;One question per post&quot;, get someone to explain it to you.


For your first question, use the following rules:


1.  If the slopes are equal, the lines are parallel.


2.  If the slopes are negative reciprocals, then the lines are perpendicular.


3.  Otherwise, the lines are neither parallel nor perpendicular.
