Thank you for your reply!
So, y.n for point 2 has nothing to do with point 1, correct?

Also, since w.0, w.1 and w.2 are different numbers, do you need multiple points to assess the values of the three w's?

Further, is updated w like an array, dependent on which n is being chosen, or is it one uniform number that is applied to all x's?
