The correct option is B
y- axis only
The given equation can be written as (x−4)2+(y+2)2=42.
We know that the standard equation of the circle with centre (h
) is (x−h)2+(y−k)2=r2.
Comparing the given equation with the standard equation, we get centre ≡
(4, -2), and radius = 4.
Since co-ordinates of the centre of the circle are (4, -2), therefore the given circle touches y
