Math Problem Statement
are the vectors -2i + 2j - 3k and 2i + 4j -5k colinear
Solution
To determine if the vectors and are collinear, we check if one vector is a scalar multiple of the other. That is, we need to see if there exists a scalar such that:
Given:
We equate the components of to times the components of :
Solving for from each equation:
Since is not the same for all three components, the vectors are not collinear.
