It's for the first chapter which is Geometry and Algebra Prequisites o.o So basically it's the review chapter :O
Oh, btw... Slope gets a name change later on :O When you deal with Parabolas (which are U thingies) you deal with Average Rate of Change which is the same thing :O
You know... one of the things they teach you later in Algebra is how to make graphs without ploting anything or using a graphing calculator :O I could teach you how o.o It's really easy too~
Things are going well for me I suppose... I have my first exam for Trig. on Thursday which shouldn't be too hard. The hardest thing on there is Sin, Cos, and Tan o.o
