What are the coordinates of (4,9) rotated 90 degrees clockwise
To rotate a point 90 degrees clockwise, you can swap the x and y coordinates, and then negate the new x coordinate.
Let's apply this to the point (4, 9):
Swapping the x and y coordinates, we get (9, 4).
Negating the new x coordinate, we get (-9, 4).
So the coordinates of (4, 9) rotated 90 degrees clockwise are (-9, 4).
