hi, can someone suggest a book/resource which teaches to plot lines, planes etc.. for instance, I want to visualize difference between the following 2 planes. x+y+z=0 and x+y+2z= 0 (Notice difference in z coefficient)

Basically want to know the geometric interpretation of linear algebra ? i.e. why are non singular , invertible matrixes have solutions ? Or proof of them ?
