To rotate a point 90 degrees counterclockwise, we swap the x and y coordinates and negate the new x coordinate.
In this case, if we swap the x and y coordinates of A, we get (4, 2). Negating the new x coordinate gives us (-4, 2).
Therefore, the new point after rotating 90 degrees counterclockwise is (-4, 2).
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)

are you sure..
I apologize for the confusion. Let's reevaluate the rotation.
To rotate a point 90 degrees counterclockwise, we can apply the following transformation:
New x-coordinate = -old y-coordinate
New y-coordinate = old x-coordinate
For point A(2, 4), the new x-coordinate would be -4 and the new y-coordinate would be 2.
Therefore, the new point after rotating 90 degrees counterclockwise is (-4, 2).
So, the correct answer is (−4, 2) or 'left parenthesis negative 4 comma 2 right parenthesis'.
