If point A' (9, 4) undergoes a rotation of 90° counterclockwise, the new coordinates would be:
A'' = (-4, 9)

If point A (1, 3) is reflected over the y-axis, the x-coordinate will be negated while the y-coordinate remains the same. Therefore, the coordinates of A' would be:
A' = (-1, 3)
Similarly, if point B (3, 6) is reflected over the y-axis, the x-coordinate will be negated while the y-coordinate remains the same. Therefore, the coordinates of B' would be:
B' = (-3, 6)
A' = (-1, 3)
Similarly, if point B (3, 6) is reflected over the y-axis, the x-coordinate will be negated while the y-coordinate remains the same. Therefore, the coordinates of B' would be:
B' = (-3, 6)
