Quick math joke

Saw this joke on the xkcd forums today posed by Pippin:


Two of my friends in math class today:
“Dude, our slope is so undefined!”
“Straight up, bro.”

Spoiler hint: What is the slope of a horizontal straight line?

Another one from that forum:

Why don’t jokes work in base 8?
Because 7 10 11.
