Question

An image point has coordinates B'(7,-4). Find the coordinates of its pre-image if the translation used was

(x + 4, y + 5).
B 3.1
B[3.-9)
B|11,-9)
B/11, 1)

Answer 1

B

Explanation:

To go from B' to B , perform the inverse operation

That is the translation rule is (x - 4, y - 5 ) , then

B'(7, - 4 ) → B (7 - 4, - 4 - 5 ) → B (3, - 9 ) → option B
