Linear algebra is the study of linear operations in vector spaces. An example of a vector space is the infinite set of all possible Cartesian coordinates in two dimensions in relation to a fixed point referred to as the origin, and each vector (i.e., a 2-dimensional coordinate) can be viewed as a member of this set.
