I don't understand how one visualizes in row pictures of equations. There is an example in the book:(adsbygoogle = window.adsbygoogle || []).push({});

With A=I(the identity matrix)

1x+0y+0z= 2

0x+1y+0z= 3

0x+0y+1z= 4

They drew these in the xyz plane. I don't know how they did this, can someone explain me that?
