Point A is located at (3, -5). After it is transformed, point A' is located at (3, 5). How was the point transformed?

A. It was reflected in the x-axis.
B. It was rotated 90° around the origin.
C. It was reflected in the y-axis.
D. It was rotated 180°.

Respuesta :

Answer:

A

Step-by-step explanation:

Under a reflection in the x- axis

a point (x, y ) → (x, - y )

Under a rotation about the origin of 90°

a point (x, y ) → (- y, x )

Under a reflection in the y- axis

a point (x, y ) → (- x, y )

Under a rotation of 180°

a point (x, y ) → (- x. - y )

Here A(3, - 5 ) → A'(3, 5 ) → A
