we met the teachers

last night.  The first day of pre-calculus is obviously going over class rules, introductions, course requirements and goals.  On the calendar for the second day is:
Plot points in the Cartesian plane, apply the distance and midpoint formulas

I honestly have no idea what that means.  I'm picking up on keywords and assuming this has something to do with graphing but omg.  I'm clueless.  I would post a video but I can't think of anything after reading the second day agenda.  My brain is worn out.
