He center of a circle represented by the equation (x + 9)2 + (y − 6)2 = 102 is
2 answers:
centre = ( - 9, 6)
the equation of a circle in standard form is
(x - a)² + (y - b)² = r²
where (a , b) are the coordinates of the centre and r is the radius
(x + 9)² + (y - 6)² = 102 is in this form
with centre = ( - 9 , 6 )
