(3,- 5)
(-3, 5)
(-5, 3)

$$(x-h)^2+(y-k)^2=r^2$$the equation of a circle with center at (h, k) and radius r.

h = the number you put in for x to make the inside = 0

for yours, x+3 is inside so what value of x makes it 0?  that's h.

same method/ideology goes for k.

So number 1 ?

anonymous · Answer

what's number 1?

anonymous · Answer

(3,- 5)

anonymous · Answer

well... put in 3 for x.  does 3 + 3 = 0?

anonymous · Answer

well no , so my second guess would be (-3, 5) ?

anonymous · Answer

why would you guess?  look, set x+3 = 0 and slove for x.  that will be the x coordinate of your center.

do the same with y, i.e., set y-5=0 and solve for y. that will be the y coordinate of your center.

do it like that and you'll never have to guess!
