An image Point has coordinates B'( 7, -4 ). Find the coordinates of its preimage if the translation used was (x + 4, y + 5 ).
B(11,1)
B(3,1)
B(3,-9)
B(11,-9)
Pls help.thx y'all

Given that the image point has coordinates B'(7,-4).

The coordinates of its preimage if the translation used was

We need to determine the coordinates of the preimage.

The coordinates of the preimage:

The coordinates of the preimage of the point B' can be determined by substituting the points of B' in the translation.

Thus, we get;

Substituting the coordinates, we have;

Simplifying, we get;

Therefore, the coordinates of the preimage is B(11,1)

Hence, Option A is the correct answer.
