Question

Sumy is working in geometry class and is given figure ABCD in the coordinate plane to reflect. The coordinates of point D are (a, b) and she reflects the figure over the line y = x. What are the coordinates of the image D'? (a, –b) (b, a) (–a, b) (–b, –a)Sumy is working in geometry class and is given figure ABCD in the coordinate plane to reflect.

(a, –b)
(b, a)
(–a, b)
(–b, –a)

Answer 1

(b, a)

Explanation:

Example if D was (3, 2) and reflects across y = x, D' will be (2, 3)
