Let T: R2 - R2 such that 7(1, 0) = (1, 0) and T(0, 1) = (0, 0). (a) Determine T(x, y) for (x, y) in R2. (b) Give a geometric description of T. O T is the projection of every vector in R onto the y-axis. O T is the projection of every vector in R onto the x-axis. O T is the projection of every vector in R2 onto the z-axis. O T maps every vector in R2 to its orthogonal projection in R. O T maps every vector in R to its orthogonal projection in the xy-plane
