I've been going through the book for the past 3 hours teaching myself what i need to know for my quiz tomorrow and doing the homework associated with each section. The question is:
What's the difference between a line with zero slope and a line with an undefined slope?
It's not in the answer section in the back of the book so I figured I'd just ask you guys
