Polygon K(1, 0), L(8, 3), M(9, 4), N(2, 1) was mapped to polygon O(-1, 1), P(20, 10), Q(23, 13), R(2,4). What was the similarity transformation?

• translate:(x, y) → (x-2, y+1)

• first dilate: (x, y) → (3x, 3y)

  translate:(x, y) → (x-4, y+1)

• first translate:(x, y) → (x-3, y+2)

  then dilate:(x, y) → (0.5x, 0.5y)

• translate:(x, y) → (x+0, y+3)
