Homework Statement
Write down the general cartesian equation of a vertical plane (parallel to the z-axis), a
non-vertical plane and a horizontal plane (parallel to the x; y-plane) together with their
normal vectors.
Find the cartesian equations of the line of intersection of the plane
5x + y ¡ 2z = 6 (¤)
and a general horizontal plane.
How is the normal to (¤) related to the horizontal normal to the line of intersection?
Homework Equations
ax + by + cz = d
The Attempt at a Solution
It's been a while since I've been back to the Physics Forums so I'm not sure if this is the right section to post this as it is a homework question but I actually have no idea how to solve it.
I've been given a clue that the general cartesian equation of a vertical plane (parallel to the z-axis) is ax+by-c=0, however I do not understand why - I can only guess at best.
I only need help with getting the general cartesian equations, so if anyone could provide some tips or a link to materials about planes it would be great!
Thank you.
EDIT: Nevermind please close, I kinda understand it now.
