Find the scаle fаctоr fоr the dilаtiоn shown. Enter any fractions as a/b. A coordinate plane shows two parallelograms, one large in black and one smaller in red. The black parallelogram has vertices A at (−9, -2), D at (3, -2), E at (9, 6), and M at (−3, 6), with horizontal top and bottom sides. The red parallelogram lies inside the black one, with vertices A′ at (−3, -1), D′ at (1, -1), E′ at (3, 2), and M′ at (−1, 2).
