Given point A (2, 4) on the triangle in Quadrant I, where is the new point if the triangle is rotated 90 degrees counterclockwise ? (1 point) (4, - 2); (- 4, 2); (- 2, - 4); (- 4, - 2)

To rotate a point counterclockwise by 90 degrees, we need to swap the x and y coordinates and negate the new x coordinate.

Given point A (2, 4), the new point after rotating 90 degrees counterclockwise would be (-4, 2).

Therefore, the correct answer is (-4, 2).
