The equation, x^2+y^2=16 is an equation of the circle which is centered at (0,0), when the circle is moved 5 units to the right and 2 units down, this implies that the center will be at (5,-2)
the new equation will be:
(x-5)^2+(y+2)^2=16
Answer: B] (x-5)^2+(y+2)^2=16
Image of A (2-8, 6+4) =(-6,10)
image of B (-1-8, 5+4)=(-9,9)
