For context, I'm a 17 year old in high school

Last night I was at a Halloween party I was invited to (imagine your stereotypical high school party filled with weed and alcohol) and I learned from the hostess that a girl there I'd been flirting with was interested in me. The hostess said this girl liked me because I was cute and as intelligent as her.

So I went over and got the girl's number, and in the ensuing conversation I said "I bet I could pick you up". She asked if I meant physically, or by dating her, and I replied both. She said "I wouldn't say no". All this was said while she was drinking, however.

So now I have her number, and I'm interested in getting something, whether an LTR or just plating her, out of it. The thing is, I don't know where to go from here. What should my game plan for how to "get her" be, now that I've heard she likes me and I have her number?
