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°.

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

correct answer is b. 27/8
