I guess just a quick run though of any ideas how to get there in english would help... Any help helps!

I get the normal vector <3,0,7> and know it runs perpendicular to the plane...

I can use the point to make a parametric equation... x=4+3t y=2 z=3+7t

3x  7z = 12 <3,0,7> is the normal to this "plane" so its good for the normal for any plane parallel to it right?

given a normal and a point, all we do is put them together to get the plane equation. 3(x4)+0(y2)7(z3)=0 3x 12 7z +21 = 0 3x 7z +9 = 0 should do it
