Current Attempt in Progress
Assume that $v_1$, $v_2$, and $v_3$ are vectors in $R^3$ that have their initial points at the origin. Determine whether the three vectors lie on the
same line.
$v_1 = (0, -7, -1)$
$v_2 = (0, -14, -2)$
$v_3 = (0, -21, 0)$
Vectors do not lie on the same line.
Vectors lie on the same line.
