Triangle ABC is rotated 90* counterclockwise, reflected over the line y=x, and translated under the rule (x, y)-> (x + 4, y-2). The result has vertices at A'''(4, 7), B'''(10, -3), and C'''(-6, -8).
What were the original coordinates of vertex B?
(-1, 6)
(14, 5)
(6, 1)
(6, -1)

Triangle QRS is shown on the coordinate grid with vertices at Q (-4, 4), R (2, 6), and S (-2, -6).
If triangle QRS is dilated by a scale factor of 1/2 with the origin as the center of dilation and then reflected across the x-axis, which graph represents triangle Q''R''S''?
