Answer:

(x - 8)² + (y + 9)² = 49

Step-by-step explanation:

the equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k ) are the coordinates of the centre and r is the radius

here (h, k ) = (8, - 9 ) and r = 7 , then

(x - 8)² + (y - (- 9) )² = 7² , that is

(x - 8)² + (y + 9)² = 49
