Answer:

Option B

Explanation:

It's given that ΔE'F'G' is the translated image of ΔEFG.

Let the ΔEFG has been translated 'h' units on x-axis and moved by 'k' units on y-axis.

Let's choose a point E having coordinates (-5, -7)

By the rule of translation, coordinates of the image point E' will be,

E(-5, -7) → E'(-5 + h, -7 + k)

Coordinates of the image point E' → (-9, 4)

Comparing both the coordinates of E',

E'(-5 + h, -7 + k) = E'(-9, 4)

-5 + h = -9

h = -9 + 5

h = -4

-7 + k = 4

k = 4 + 7

k = 11

Therefore, rule for the translation will be,

E(-5, -7) → E'(-5 - 4, -7 + 11)

(x, y) → (x - 4, y + 11)

Option B is the answer.
