# Euclidean Spaces and Subspaces

1. Let W = {(a, b ,2a - 3b, -a + 2b)} whre a and b are real numbers.

(a) In what Euclidean space does this subset reside? Explain your answer.

(b) Show that W is a subspace by showing that it satisfies the closure properties.

(c) Show that W is a subspace by describing W as the span of a set of vectors.

(d) Explain why this subspace is a plane.

Thanks for using BrainMass.

(a) W consists of 4-tuples of real numbers, so W is a subset of R^4.

(b) We need to check that W is closed under addition of vectors and under scalar mutliplication (by real ...
