Answer:
[tex](x+9)^{2} +(y+12)^{2}=225[/tex]
Step-by-step explanation:
Remember that the center of a circle is written in (h,k) format. So h= - 9 and k = -12. Also, the distance between those two points is 15 units, so r = 15.
So the formula [tex](x-h)^{2} +(y-k)^{2}=r^{2}[/tex]
Should look like [tex](x+9)^{2} +(y+12)^{2}=225[/tex]
