To rotate a point counterclockwise by 90 degrees, we switch the x-coordinate with the y-coordinate and multiply the new x-coordinate by -1.
So, the new x-coordinate is -4 and the new y-coordinate is 2.
Therefore, the new point is (-4,2).
The answer is B. (-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?
