Question 1164682
<font face="Times New Roman" size="+2">


Calculate the slope of the line represented by the first equation and call it *[tex \Large m_1].  Calculate the slope of the line represented by the second equation and call it *[tex \Large m_2]



If *[tex \LARGE \ \ m_1\ =\ m_2\ \ ] then the lines are parallel.


If *[tex \LARGE \ \ m_1\ =\ -\frac{1}{m_2}\ \ ] then the lines are parallel


If neither relationship holds, then the lines are neither parallel nor perpendicular.

My calculator said it, I believe it, that settles it
