I'm having trouble visualizing what the graph of the plane x + y + z = 2 looks like. It is easier for me to graph equations of 2 variables. Also, I thought equations of 2 variables are "planes", while equations of 3 variables are of a solid? Is there any steps to follow or something to graph these equations of 3 variables?(adsbygoogle = window.adsbygoogle || []).push({});
