Is W a subspace of the vector space? If not, state why. (Select all that apply.) W is the set of all vectors in R2 whose components are rational numbers. O w is a subspace of R2. O w is not a subspace of R2 because it is not closed under addition. O wis not a subspace of R2 because it is not closed under scalar multiplication.

Linear Algebra

In mathematics, problems can be solved by the arithmetic operators like addition, subtraction, multiplication, and division. In algebra, we represent the numbers by any letter called a variable. If these variables are of degree 1, then it is studied under linear algebra. The first-degree equations involving algebraic expressions are called linear equations. That is, if you represent it by drawing a graph you will get a straight line.
