Square ABCD was translated using the rule (x, y) → (x – 4, y + 15) to form A'B'C'D'. What are the coordinates of point D in the pre-image if the coordinates of point D’ in the image are (9, –8)?

(13, –23)
(5, 7)
(18, 1)
(–6, –4)

Respuesta :

Answer: the rule is  (x, y) → (x – 4, y + 15)

D’ in the image are (9, –8)?

x – 4= 9  y + 15= -8, so x=13, and y = - 8-15=-23

so D(13, -23)
