Graphing a plane

  1. Sep 8, 2013 #1
    Hey, how would I graph the plane x + 2y + 3z = 0. We were taught to find the x,y and z intercepts and then connect them resulting in the plane. In the following equation, I get the points x=0,y=0 and z =0. I can see that the intercept approach doesn't work for this question. What else can I try?

    hi baddin! :smile:

    draw the line x + 2y = 0 on the x-y-plane, and the line x + 3z = 0 on the x-z-plane, and join them :wink:
