Answer: (- 5, 4)
Justification:
The question asks for the coordinates of the image produced by the composed rotation - 270° o - 90° to the point (-5,4); that means applying a first rotation of - 90° and a second rotation of - 270°.
That composition of rotation is equivalent to one rotation of (- 270°) + (-90°) = - 360°.
A rotation of - 360° means 360° clockwise; that is a complete turn, to lead the original point to itself.
Then, the image of the point (- 5, 4) is the same point ( - 5,4)
