Figure EFGH on the grid below represents a trapezoidal plate at its starting position on a rotating surface: A trapezoid EFGH drawn on a 4 quadrant coordinate grid with vertices E is at negative 4, 8. F is at negative 7, 5. G is at negative 4, 3. H is at negative 2, 5. The plate is rotated 90° about the origin in the counterclockwise direction. In the rotated trapezoid, what are the coordinates of the endpoints of the side congruent to side FG?
