A quadrilateral is plotted on a coordinate plane with both the axes ranging from negative 10 to 10. with Pre Image A (-8, -5), Pre Image B (-4, -2), Pre Image C ( -2, -5), Pre Image D (-4, -8)
Imagine a 90° (counterclockwise) rotation about the origin of the figure in the image. Select the coordinate of D′ .

To find the new coordinates after a 90° counterclockwise rotation of point D (-4, -8) about the origin, we can use the rotation transformation formula:
For a point (x, y), the coordinates after a 90° counterclockwise rotation will be (-y, x).
Applying this to point D (-4, -8):
So, the new coordinates D' will be (8, -4).
Thus, the correct response is: (8, -4).
