What is the shortest distance from the point (x,y,z) to (a) the xy-plane (b) the x-axis?
Could someone please explain this one, maybe with a (x,y,z) graph if possible?

That's what I think of (a), shouldn't that be somewhat correct? Just get rid of the z and you're on the xy-plane

Shouldn't that be the shortest lenght to x?

Great, having some trouble imagining three dimentions but seems like I'm starting to grasp it
