Question 465677: let v1=(-3,2,4), v2=(-3,5,0), and y=(-18,24,h)
for what value of h is y in the plane spanned by v1 and v2?

The matrix must have rank less than 3.
After reducing to row echelon form, the matrix becomes .
==> h = 8 for linear dependence.
==> y is in the plane spanned by v1 and v2 if h = 8.
