    the equation of a plane is defined by its "normal vector" if we know the normal vector N, then N dot P = b would be the equation, where P=<x,y,z> represents any point on the plane and b is a scalar.

    for ** plane that is parallel to the xy -plane ** any idea what vector is normal to the xy plane ?

    we denote a vector by either using ai + b j + c k or <a,b,c> either way, it means the same thing. put the tail at <0,0,0> and draw a "line" to point <a,b,c> and then put an arrow head at the end.

    there are lots of vectors that point straight up from (0,0,0) (i.e. depends on the length we make the vector) but if we want to point up 1 unit in the z-direction any idea how to write that vector?

    @phi can you just solve this for me and i will see how you did it Determine a vector equation for the plane that is parallel to the xy -plane and passes through the point (4, 1, 3).
