Question

PLEASE HELP AND ILL GIVE BRAINLIEST ​

Answer 1

Answer:

2

Step-by-step explanation:

Subtract the number with the term both sides ( which is 9)

${x}^{2} + {y}^{2} - 6x + 4y = - 9$

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.)

${x}^{2} - 6x + 9 + {y}^{2} +4y + 4 = - 9 + 9 + 4$

$(x - 3) {}^{2} + (y + 2) {}^{2} = 4$

Take the square root of the right side to find the radius

$\sqrt{4} = 2$
