Answer;

B' (6, -11)

Explanations:

Translations is a transformation technique used to change the position of an object in an xy-plane.

Given the coordinate of a triangle ABC given as A (10, 7) B (4, -4) C (- 11, -9). If it is translated right 2 and down 7, the translation rule will be;

(x, y) -> (x+2, y-7)

Determine the new point B'

B' = (4+2, -4-7)

B' = (6, -11)

Therefore the coordinate of the new point B' is (6, -11)
