please answer the linear algebra question

Let y = 4 W2 = 7 w and W = span(W1, W2) . Select the vector below equal to projw (V) . ***WARNING***: there are two steps here because the vectors { W1, w2 } are not orthogonal. So first, you apply Gram-Schmidt to turn the set into an orthogonal basis, say {ul, uz } where W = span(u1, u2) . Then, you can compute the projection using the usual formula for the coefficients in an orthogonal basis. (a) A w (b) 3 3/2 (C) 7/2 -7/2 (d) 9/2 5
