Question

What are the coordinates of point F after a 90° clockwise rotation about the origin?

O A (-5,3)

C. (3,-5)

O B. (-3,5)

O D. (3. 5)

Answer 1

From the graph given, the coordinates of point F are:

(x, y) ==> (-5, -3)

Using rotation rules, after a 90° clockwise rotation about the origin, (x, y) becomes (y, -x)

Thus, after a 90° clockwise rotation, we have:

(x, y) ==> (y, -x)

(-5, -3) ==> (-3, 5)

Therefore, 90° clockwise rotation about the orign, the coordinate.
