    Lines through/parallel to planes?

    The question is:
    If the positive z-axis points upward, an equation for a horizontal plane through the point (-3,-2,4) is:

    An equation for the plane perpendicular to the x-axis and passing through the point (-3,-2,4) is:

    An equation for the plane parallel to the xz-plane and passing through the point (-3,-2,4) is:

    I have a test on this TUESDAY, and any help with these would be greatly appreciated.

    If a,b,c)" alt="Pa,b,c)" /> is a point in \math{R}^3 then:
    x=a is a plane parallel to the yz\text{-plane} which contains P.
    y=b is a plane parallel to the xz\text{-plane} which contains P.
    z=c is a plane parallel to the xy\text{-plane} which contains P.
