I'm tutoring a friend in college algebra. She probably one of the most anal people (structured) I know, yet she cannot get basic college algebra. I've explained that one must follow the rules. She is learning graphing...basic Y= mx+b. She doesn't understand that b = y - intercept. Why doesn't y = y - intercept? m = slope but why doesn't x = x intercept? Arrrgh! HELP!
