Which series of transformations results in the image being congruent to the pre-image?

(x, y) → (–0.25x, –0.25y)
(x, y) → (x, y + 9)
(x, y) → (x, –y)

(x, y) → (x – 1, y)
(x, y) → (–x, –y)
(x, y) → (3x, 3y)

(x, y) → (x, –y)
(x, y) → (x + 2, y)
(x, y) → (x, y – 7)

(x, y) → (x, – y)
(x, y) → (x, 2y)
(x, y) → (x + 5, y)
