I don't know if I'm having a brain fart or what but I'm drawing a blank...
What is the slope of a line perpendicular to x - 3y = 9?
Notes:
Perpendicular lines have slopes that are negative reciprocals of each other.
Example: So, if the original line has a slope of -3/2, the line perpendicular to the original line has a slope of 2/3.
So, if I work that problem out, I get...
-3y = 9 - x
y = 9 - x/-3
y =
That is where I'm locked up...what do I do with the x? It's been a while since I've done this (The last time I turned any homework in in this class was eight days ago. I've been juggling catching this class up and keeping up in Chemistry so... ) so I'm, more than likely, just having a brain fart.
