Answer:

(x, y) → (x + 4, y - 3)

Explanation:

If a point (x, y) is translated by 'a' units to the right and 'b' units down, new coordinates of the image point will be,

(x', y') → (x + a, y - b)

By applying this rule in the picture attached,

Coordinates of A → (-4, 2)

Coordinates of A' → (-4 + a, 2 - b)

Since, coordinates of A' are (0, -1)

Therefore, (-4 + a, -2 - b) = (0, -1)

Comparing coordinates on both the sides,

-4 + a = 0 ⇒ a = 4

2 - b = -1

b = 3

Therefore, rule for the translation will be,

(x, y) → (x + 4, y - 3)
