Which translation rule matches the transformation for congruent triangles?

Responses

(x, y) → (x + 4, y - 9)
(x, y) → (x + 4, y - 9)

(x, y) → (x - 9, y + 4)
(x, y) → (x - 9, y + 4)

(x, y) → (x - 6, y - 8)
(x, y) → (x - 6, y - 8)

(x, y) → (x - 8, y + 4)
(x, y) → (x - 8, y + 4)

why repeat them?
since they are all just translations, they will not change any lengths, so any triangle so transformed will be congruent with the starting shape.
