Anyone else having trouble understanding the answer to the problem at link below? I would think one of the weights would have to be negative.

Thanks for any help, Scott

TopNewest@Scott Edwards - The slope of the line is negative, so both of the weights should be positive (since the decision boundary is of the form \(w_1x_1+w_2x_2 + b = 0.\) The slope is \(-w_2/w_1.\)

In the future, if you think a problem is flawed, you can report it directly on the problem. See here for details.

Can you explain why you think the solution given is flawed?
