## Homework Statement

write the equation of the plane that contains the point(-1, 2, -2) and satisfies

1. parallel to xy plane

2. orthogonal to z-axis

3.parallel to both the x and z axes

4. parallel to the plane x-y+3z = 100 (plane A)

## Homework Equations

## The Attempt at a Solution

i started with finding the normal of plane A which is <1,-1,3>

and i know that the normal of this plane should be the normal of my plane suince they're

parallel

but what i don't get is how the plane I am finding can be orthogonal the the z axizs and parallel to it at the same time...

i drea it and it still doesn't look like it makes sense

i don't know where to go from here...
