# Is this answer on Neural Networks right?

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

@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. Staff · 1 month, 4 weeks ago
