Respuesta :
Answer:
( x + 5 )² + ( y + 4 )² = 29
Step-by-step explanation:
Equation of the circle is
( x - h )² + ( y - k )² = r²
( h, k ) are coordinates of the center
~~~~~~~~~~~~~~~~~~~~~
Coordinates of the center of the circle are
( [tex]\frac{-3-7}{2}[/tex] , [tex]\frac{-9+1}{2}[/tex] ) = ( - 5 , - 4 )
d = 2√29 ⇒ r = √29
( x + 5 )² + ( y + 4 )² = 29
