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

A'' = (-4, 9)

If point A' (9, 4) undergoes a rotation of 270° counterclockwise, the new coordinates would be:

A''' = (4, -9)

B (3, 6) are reflected over the y-axis. Click Here for Help Video



A






B
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)
