You should be proud of yourself.  You got very far on this test, farther than most, but the correct answer is y = 1x + b.

The good news is that you can skip Volumes 1 and 2 of the Learn Math Fast System and start with Volume 3.  That book will teach you prealgebra in about a month.  If you made a simple mistake, but know how to write a linear equation, you could probably start with Volume 4.  But if these last 10 questions were challenging, start with Volume 3.  Use coupon code PT2026 to get 10% off your order.
