Which sequences of transformations result in the image being congruent to the pre-image? choose all answers that are correct. (x, y) → (x + 4, y) (x, y) → (x, –y) (x, y) → (x, y – 2.5) (x, y) → (x – 5, y – 5) (x, y) → (0.5x, 0.5y) (x, y) → (x, –y) (x, y) → (x + 1, y + 1) (x, y) → (–x, y) (x, y) → (3x, 3y) (x, y) → (–x, y) (x, y) → (x, y + 9) (x, y) → (x – 7, y)
