What are the coordinate points (4,9) rotated 270 degrees counter clockwise

1 answer

To rotate a point (x, y) counterclockwise by 270 degrees, the new coordinates are given by (-y, x).

For the point (4, 9):

New x-coordinate = -9
New y-coordinate = 4

Therefore, the coordinate points (4, 9) rotated 270 degrees counterclockwise are (-9, 4).
