Question
find an equation for a plane parallel to the xy-plane; does not pass through the origin.
(I know how you would find the equation if it says passes through a certain point. But I'm confused how to do it if it says does not pass through certain point)

the plane
z = k
is parallel to the x-y plane at a distance |k|
The x-y plane is the plane z=0
(which, or course, does pass through the origin)
