Answer:

Center= (-9,6) Radius=5

Step-by-step explanation:

correct answer:

( x + 9 ) ² + ( y - 6 ) ² = 25

center = ( -9, 6 )

radius = 5

equations:

we know from the given equation that the center would be (-9, 6) because we have to plug into the equation; ( x – h ) ² + ( y – k ) ² = radius²

how to find the center coordinates:

if youre confused on how we got the -9, by using the negative addition rules:

x - (-9) we can simplify that to ( x + 9 ) like shown above so that how we got -9. It's a little easier to find the 6 because its just x - 6 so we dont have to simplify anything its just 6.

how to find the radius:

the radius is a little more difficult to find, but, since we are given 25, we can just type the square root of 25 (√25) which would be 5!

thats it!! hope this helps<3
