Okay thank you and I'm sorry

misty1212 · Answer

$$(x-5)^2+(y+3)^2=25$$ looks like $$(x-h)^2+(y-k)^2=r^2$$ you have to identify $h, k, r$

misty1212 · Answer

this is an overlooked but important skill, recoginizing the specific from the general
in this case $h=5,k=-3$ and since $r^2=25$ you know $r=5$

misty1212 · Answer

that means your circle has center $(5,-3)$ and radius $5$

misty1212 · Answer

since $(5,-3)$ is the center of the circle, it is certainly in the interior of the circle
