Answer: 
Step-by-step explanation:
Given
The point C
is rotated
clockwise about the origin
If a point is rotated
about the origin, then the sign of the co-ordinates changes without changing the order of coordinates.
So,C
becomes C'
after the rotation.
It would be (6,9) from the given end point to the given middle point it is a 7 point difference, so we add 7 to the y value to get the other endpoint, hope it helps!
