Holy cow! THAT is only worth 15 points?! I hope you understood those explanations, cause a few of them had my head spinning (another reason I'm a librarian, NOT a math teacher!).

I'm helping an 8th grader with Algebra 1, and thank goodness Prentice Hall(the publisher of the math book) has an online guide and tutoring video manual. It's amazing how much you forget when you don't use it!
