1 Describe the column space of these matrices : a point, a line, a piac, ani or

3D

.\

A_(1)=[[2,2],[1,1],[5,6]],A_(2)=[[1,0,0],[1,1,0],[1,1,1]],A_(3)=[[1,5],[2,10],[1,5]],A_(4)=[[0,0],[0,0],[0,0]]

\ 2 Find a combination of the columns that produces

(0,0,0)

: column space = plane. The trivial combination (zero times every column) is not allowed.\ Which columns are dependent on earlier columns?\
