Visualize plane given by this equation

  1. Nov 28, 2009 #1
    Dear users,

    I'm wondering if it is possible to visualize function (plane) given by this equation:

    Ax + By + Cz - D == 0

    I tried to use Plot3D function, but it allows only 2 variables.

    How to do that?

    Ax + By + Cz - D = 0
    <==> Cz = -Ax - By + D
    <==> z = -(A/C)x - (B/C)y + D/C, assuming C isn't 0.
    Now you have z as a function of the variables x and y.
