# Parameters of W for the equation $$W^TX$$ in SVM

In support vector machine if there are 2 features then the 2 features can be separated using a line. To decide the position of an unknown point we use the equation $$W^TX$$. If we get the positive value of the calculation the point should be in one side, if we get the negative value for the calculation the point should be in the other side.

Here the parameter of W is (m(slope), c(y intercept)), when the equation of line is y=mx+c.

1. I would like to know when there are 3 input features and the separating line became a plane what are the parameters for W?

2. If $$W^TX$$ represent the equation of an hyperplane (more than 3 input features) what are the parameters of W?
