equation x+3y+2z=6

how would you sketch the plane on a set of axes? is it supposed to look like a triangle? becuse my paper says it makes a trangular pyramid. i don't get it

  • geometry -

    draw dot for (0,0,0)
    draw z axis up from the dot
    draw x axis toward lower right from dot
    draw y axis toward upper right from dot
    when x and y are 0, z = 3, mark spot (0,0,3)
    when x and z are 0, y = 2, mark spot (0,2,0)
    when y and z are 0, x = 6, mark spot (6,0,0)
    Note the three spots make a pyramid.
    when x and
