**Prove that two vectors are linearly dependent (taken as a set of vectors) if and only if one vector is a multiple of the other.**

This statement explores the concept of linear dependence in vector spaces. If two vectors are linearly dependent, it means that they lie along the same line in a vector space, implying that one is a scalar multiple of the other. Essentially, neither vector adds a new dimension to the span of the set, leading to a dependency between them. Understanding this relationship is crucial in linear algebra, as it forms the basis for more complex analyses of vector spaces and their dimensions.
