Question

Which transformation will result in an image that is congruent to its pre-image?

(x, y) → (−x, −4y)
(x, y) → (4x, y − 4)
(x, y) → (−4x, y)
(x, y) → (−x, −y)

Answer 1

Any translation but dilation will result in a congruent image

Anything that has x or y multiplied by something can be eliminated :)

Answer 2

thank youuuuu
