Answer:
Option (3)
Step-by-step explanation:
If a point having coordinates of a point (x, y),
If this point is rotated by an angle of 90 degrees clockwise about the origin then the coordinates of the image will follow the rule,
(x, y) → (y, -x)
If a point A is (3, -9) and this point is following the the same rule, new image point will be,
A(3, -9) → A'(-9, -3)
Option (3) will be the correct option.
