To rotate a point counterclockwise around the origin (0, 0) by 270 degrees, you can use the following transformation for the coordinates (x, y):
\[ (x, y) \rightarrow (y, -x) \]
Given point A (2, 4), let's apply the transformation:
- Identify x and y: Here, x = 2 and y = 4.
- Apply the transformation:
- New x-coordinate = y = 4
- New y-coordinate = -x = -2
Therefore, the new point after rotating point A (2, 4) by 270 degrees counterclockwise is (4, -2).
So the correct response is:
(4,−2)
