Rectangle ABCD is reflected over the y-axis. What rule shows the input and output of the reflection, and what is the new coordinate of A'? (1 point) Rectangle ABCD is shown. A is at negative 5, 1. B is at negative 5, 3. C is at negative 1, 3. D is at negative 1, 1.
A.) (x, y)→(y,−x); A' is at (1, 5)
B.) (x, y)→(−y, x); A' is at (−1, −5)
C.) (x, y)→(−x, y); A' is at (5, 1)
D.) (x, y)→(−x,−y); A' is at (5, −1)
