This is my first post to the forum and I would like to thank the book authors for the availability online and for choosing to make the book price low.

I have a question and I hope someone will help me answer it

In a 2D input space, we have the components in the W vector, w0 for the bias, and w1, w2 for the 2 dimensions of the input.

If the learning algorithm successfully found the W that could classify all input correctly, how is it possible to draw the separation line(or vector) using the 3 components of the W vector?

How could we map w0,w1,w2 to the Line equation y = ax+ b.

Thanks

Ahmed
