Select the correct location on the graph

.abc has the following transformation:
rotated 90° clockwise about the origin,
reflected across the y-axis,
and reflected again across the x-axis.

select the angle vertex that corresponds to angle a.

The vertex is (-9 , 2)

Step-by-step explanation:

∵ A = (2 , 9) , B = (6 , 2) , C = (-2 , 2)

* After rotating 90° clockwise about the origin (change sign x-coordinate

 and replace them by each other)

∴ A = (9 , -2) , B = (2 , -6) , C = (2 , 2)

* After reflected across the y-axis (change sign x-coordinate)

∴ A = (-9 , -2) , B = (-2 , -6) , C = (-2 , 2)

* After reflected across the x-axis (change sign y-coordinate)

∴ A = (-9 , 2) , B = (-2 , 6) , C = (-2 , -2)
