Oh my god! I just got a warning, ridiculous! I am posting these questions for help, hence asking!!! And I don't know the negative because I get random questions thrown at me online on my math class!

You just flip the fraction, then get a minus sign on it.
For example, if the slope of a line is 2/3, then the slope of the line perpendicular will be:
1) Flip: 3/2
2) Minus sign: -3/2

Oh ok! So when you flip a negative fraction, will that make it a positive?

Yes!
