1) insufficient b/c it gives us no information on point Y.
2) insufficient b/c it gives us no information on whether any of the two points are located inside or outside the circle.

together:

we know point x is outside the circle, (distance of 0.5 away from the point ON the circle).

xy = 9

the diameter of the circle is 8, which means the largest distance covered and the point y can still be covered inside the circle is 8.

4.5 + 4 = 8.5 (can be the maximum distance allowed for xy for y to still be a part inside the circle).

Therefore point y will lie outside the circle.
