23. Suppose a point (x, y) on the coordinate plane is rotated 270°
counterclockwise about the origin, then
reflected across the line
y= -x, then reflected
across the y-axis.
Show that the image of (x, y) after this sequence of
transformations is the same as the image of
(x, y) after a 180° rotation about the origin.

Need this asap if anyone can i would be very grateful. if you could show workings that would really
