Give the coordinates for points D and E without using any new variables. Then find the midpoint of DE. The image is of a quadrilateral DEBC drawn on a two dimensional graph. The co-ordinate of C is (-a,0) and of B is (0,-b). Vertices E and D are on x and y axis respectively. A. D(0, b), E(a, 0); midpoint of DE=(b2,a2) B. D(0, a), E(b, 0); midpoint of DE=(b2,a2) C. D(0, b), E(a, 0); midpoint of DE=(a2,b2) D. D(0, a), E(b, 0); midpoint of DE=(a2,b2)
