Question

Kite ABCD is reflected over the line y = x. What rule shows the input and output of the reflection, and what is the new coordinate of A'?

Kite ABCD is shown. A is at negative 7, 2, B is at negative 5, 3, C is at negative 2, 2, D is at negative 5, 1.

(x,y)→(y,x); A' is at (2, -7)

(x,y)→(-x,y); A' is at (7, 2)

(x,y)→(-x,-y); A' is at (7, -2)

(x,y)→(y,-x); A' is at (2, 7)
