To rotate a point (x, y) 270 degrees counterclockwise, you can use the transformation:

\[ (x, y) \rightarrow (y, -x) \]

Given the point \( A(2, 4) \):

  1. Substitute \( x = 2 \) and \( y = 4 \): \[ (2, 4) \rightarrow (4, -2) \]

Thus, after a 270-degree counterclockwise rotation, the new point is \( (4, -2) \).

The correct response is:

\((4, -2)\)
