Re: problem 1.2
So as x2 = a*x1 + b classifies the set correctly which means for every x1, x2 on this line a*x1 + b  x2 = 0 hence w0*x0 + w1 * x1 + w2 * x2 = 0 for this line.
Considering these equations can we say that a = w1, b = w0 ? Is this correct now. Further what does the part 2 means what type of picture is expected?
