Square ABCD was translated using the rule (x. y) «-4,y + 15) to form A'B'CD. What are the coordinates of point D in the pre-image if the coordinates of point D' in the image are (9, -8)?
TE
O (13, -23)
(5, 7)
O (18, 1)
O (6,4)

Step-by-step explanation:

Given

Translation:

Required

Determine the pre-image of (9,-8)

In (9,8)

and

So:

Becomes

By comparison:

Solving for (x):

Solving for (y):

Hence, the pre -image has a coordinate of

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !
