Consider the matrices whose first and second columns are given in the following pictures:
 

For each matrix in the list A,B,C,D figure out whether the matrix is invertible, then enter in "invertible" or "not invertible" in the order above.

 

I got invertible invertible invertible not invertible but it wasn't correct, could someone help me with this?

I don't know if the following is what is wanted or not (I'm guessing, based on what the vectors looked like to me!).  a, b and k are constants (not necessarily the same for each matrix).
