Answer:
2
Step-by-step explanation:
Subtract the number with the term both sides ( which is 9)
![{x}^{2} + {y}^{2} - 6x + 4y = - 9](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20%2B%20%20%7By%7D%5E%7B2%7D%20%20-%206x%20%2B%204y%20%20%3D%20%20-%209)
Complete the square for the x terms and y terms.
( To complete the square divide the coefficient term by 2 and square it, then add that product to both sides.)
![{x}^{2} - 6x + 9 + {y}^{2} +4y + 4 = - 9 + 9 + 4](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20-%206x%20%2B%209%20%2B%20%20%7By%7D%5E%7B2%7D%20%20%2B4y%20%2B%204%20%3D%20%20-%209%20%2B%209%20%2B%204)
![(x - 3) {}^{2} + (y + 2) {}^{2} = 4](https://tex.z-dn.net/?f=%20%28x%20-%203%29%20%7B%7D%5E%7B2%7D%20%20%2B%20%28y%20%2B%202%29%20%7B%7D%5E%7B2%7D%20%20%3D%204)
Take the square root of the right side to find the radius
![\sqrt{4} = 2](https://tex.z-dn.net/?f=%20%5Csqrt%7B4%7D%20%20%3D%202)
Answer:
(-8,-6)
Step-by-step explanation:
You add the equations together, the 2y and -2y cancel out. You isolate x, then plug the answer you get for x from that into one of the equations. The amount you get for y is the y-coordinate and the amount you had for x is the x-coordinate. To check, try putting the y value into the equation you didn't plug the x into before. If you get the same x value as you had before, it means it's correct, I think.
