Now I know how to solve these when there is a regular vector and point but since I can't imagine this 0x, 0z, plane, its hard for me to get started.

I don't know if this would make it clearer but in a previous excersise when he had the question: Write the equation of a plane which is parallel to the plane x0y and crosses through M(2,5,3). We basicly used the z cordinate vector(0,0,1) to be perpendicular to the plane we were trying to find.
