Show that $\left(\begin{array}{r}-3 \\ 7 \\ 6 \\ 1\end{array}\right)$ is in the subspace of $\mathbb{R}^4$ spanned by $\left(\begin{array}{r}1 \\ -3 \\ -2 \\ 0\end{array}\right),\left(\begin{array}{r}-2 \\ 6 \\ 3 \\ 4\end{array}\right)$ and $\left(\begin{array}{r}-2 \\ 4 \\ 6 \\ -7\end{array}\right)$.

Key Concepts

Vector Subspace

A vector subspace is a subset of a vector space that is closed under vector addition and scalar multiplication. In this context, the subspace of ?? consists of all linear combinations of a given set of vectors. It provides the structure within which you can determine if a particular vector can be expressed using other vectors from the subspace.

Span

The span of a set of vectors is the collection of all possible linear combinations of those vectors. Demonstrating that a vector belongs to the span of other vectors means proving that it can be written as such a combination. The span forms a subspace of the vector space and identifies all the vectors that can be reached using the given set.

Linear Combination

A linear combination involves creating a new vector by multiplying each vector in a set by a scalar and then adding the results. To show that a given vector is in the span of other vectors, one must express it as a linear combination of those vectors, identifying the appropriate scalar weights that produce the target vector.

Systems of Linear Equations

Solving a system of linear equations is a key method in determining whether a vector can be written as a linear combination of a set of vectors. By setting up equations that equate the components of the given vector with the corresponding components of the linear combination, one can solve for the scalars, thus confirming membership in the subspace if a solution exists.
