The correct options for the linear combinations of the vectors are given by:
A, B, C, D, E and F.
The span between two vectors is the set that contains all linear combinations between these two vectors.
Supposing we have two vectors u1 and u2, as is the case in this problem, the infinitely many linear combinations have the following format:
k1u1 + k2u2
In which k1 and k2 are real numbers.
With k1 = 4 and k2 = -7, we get that option A is correct.
For option B, we have to see if it is possible to solve the following system.
The solution is k1 = k2 = 0, which are real numbers, hence option B is correct.
Both vectors u1 and u2 are part of the span, hence options D and F are correct. The size of the span is of infinity, hence option E is correct while option G is not.
The dimension of the span is of 3, as the vectors have 3 elements, hence option C is correct.
