Start by reading the definition of linear independence

A set of vectors is linearly independent if no vector in the set is (a) a scalar multiple of another vector in the set or (b) a linear combination of other vectors in the set
:
for example, the following row vectors are linearly independent
:
v1 = (2, 4, 6)
v2 = (0, 1, 0)
v3 = (0, 0, 1)
:
that should get you going
:
Note that if we have
:
v1 = (1, 2, 3)
v2 = (4, 5, 6)
v3 = (5, 7, 9)
:
then (v1, v2, v3) is linearly dependent since v3 is a linear combination of v1 and v2
