Graph Plane x+2y+3z=0 | Math Tutorials

[baddin]

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?

easy-peasy …

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

Thanks for your help, it looks correct! =D
