Aug 23 comment Formula for number of lines you can draw through $n$ points All of you were a lot of help, but Andre got closest to the answer. My math teacher gave me credit for my answer, but he also said that the following answers were correct: $$\frac{1}{2}n(n-1)$$ and $$\sum_{i=1}^{n}(i-1)$$ The first one is pretty much exactly the same as Andre's answer: $$\frac{n(n-1)}{2}$$ Aug 23 awarded Scholar Aug 23 accepted Formula for number of lines you can draw through $n$ points Aug 23 awarded Supporter Aug 23 comment Formula for number of lines you can draw through $n$ points Yes, sorry. "drawn through any two of $n$ points" is correct. also, no, this is why i say i think my answer is too complicated. I'm in a basic Geometry class. I have a separate understanding of math from the class i'm in, so I understand the other answers, but these seem too complicated to be the actual answer, because i'm in such a basic class.
