(2 points) Let V = {(x, y) = R² | x = y} U {(x, y) = R² | x = −2y Complete the following statements to determine if V is a subspace of R². (a) Vis ? If it is non-empty, give two different examples of vectors in V. If it is empty, then leave the following spaces blank. example 1: a = example 2: b = ( Note: Normally, only one example is required to show V is not empty in a proof. (b) Vis ? ✓under vector addition. If it is not closed, enter two vectors a, b € V below, whose sum is not in V. If it is closed, then leave the following spaces blank. a = b = (c) Vis ? ✓under scalar multiplication. If it is not closed, enter a scalar k and a vector c E V below, whose product is not in V. If it is closed, then leave the following spaces blank. k = and c = ( 1
