The coordinates of s are (5,4). what are the coordinates of s' after the figure is rotated 90 degrees about the origin? ,-4) b.) (-5,4) c.) (-4,5) d.) (4,5)

The general rule for 90° counterclockwise rotation about the origin is given by:
(x,y)→(-y,x)
thus given that S has coordinates of (5,4), then rotation through 90° will map the the figure on S'(-4,5). Hence the answer is:
C](-4,5)
