Δabc with vertices a(-3, 0), b(-2, 3), c(-1, 1) is rotated 180° clockwise about the origin. it is then reflected across the line y = -x. what are the coordinates of the vertices of the image?
a'(0, 3), b'(2, 3), c'(1, 1)
a'(0, -3), b'(3, -2), c'(1, -1)
a'(-3, 0), b'(-3, 2), c'(-1, 1)
a'(0, -3), b'(-2, -3), c'(-1, -1)
