Answer 1

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:

\((4, -2)\)
