Answer:
Think of it like a number line. If you start at 2 and move three to the left you land on -1.
Recall,
Circle centered at (h,k) and radius r --

Here it is a circle centered at (h,k)=(5,6) and radius r=6
If you move to the right, the x coordinate will increase, so here the only change is the x coordinate increases by 2.

Your point (0,0) on the blue shape, when translated to the green shape, becomes (-6,-8)
