Question

The equation of a circle is (x + 1)^2 + (y + 3)^2 = 25. Which graph best represents the circle?

Answer 1

looks like \((x-h)^2+(y-k)^2=r^2\) identify the center as \((h,k)\) and the radius as \(r\)

Answer 2

@satellite73 how would i apply that to the graphs/

Answer 3

look for the one with radius \(r\)
since \(r^2=25\) you know \(r=5\)

Answer 4

also you know that the center is \((-1,-3)\)

Answer 5

therefore pick the circle with center \((-1,3)\) and radius 5

Answer 6

Ok, i will look for that

Answer 7

@satellite73 It would be graph number 4?

Answer 8

i don't know let me look

Answer 9

alright

Answer 10
