How would one find the equation for the normal line to a 3-dimensional equation at a given point?

I have searched long and hard for this, but all that is discussed are tangent planes to a 3-D equation. I am aware of how to do derivates. If anyone could provide me with an equation, or a pointer in the right direction it would be much appreciated.
