Homework Statement



Which of the following vectors in R^6 are parallel to u= (-2, 1, 0, 3, 5, 1)?

a) (4,2,0,6,10,2)
b) (4,-2,0,-6,-10,-2)
c) (0,0,0,0,0,0)


I don't even know how to approach this. Can anyone help me please?

Thanks
Brad

Vectors A and B are parallel if A dot B = |A||B|. So....

or vectors are parallel if:
a = kb for some k

so write this a set of equations & see if they are consistent
