Hello : 
<span>(x + 2)² + (y-3)² = 9²
the center is : R(3 , 0 ) and radius   r = 9 
the </span> point D  is on the interior  if : RD <span>< 9
</span>the  point D  is on the exterior if :  RD > 9
 the  point D  is circumference of the circle if :RD = 9

The answer is D because The ordered pairs graphed are (2,3), (6,9), and (8,12). They all have a ratio of 2 to 3. Which means each point is 2 larger on the x-axis and 3 larger on the y-axis than the previous point. The point that is missing is (4,6) since 2 + 2 = 4 and 3 + 3 = 6.
