Vector and matrices...are the independent or dependent

Homework Statement

Determine whether the vectors v1=[1,-1;0,0],v2=[2,-2;1,... and v3=[-5,5;1,0] are independent or dependent. Find the span {v1,v2,v3} and give a description. Explain why W = [4,4;4,4,] is not in the span {v1,v2,v3}.

Homework Equations

I have tried solving this problem in matrix form...I'm not sure if this is the correct way

Use the definition of linear independence to show the vectors are independent, or show that they're dependent by writing one as a linear combination of the others. You need to show some work here before people will help.
