Answer:
(x + 7)² + (y + 10)² =13
Step-by-step explanation:
Center is at ((-4) + (-10))/2, ((-8) + (-12))/2) = (-7, -10)
distance between two pints = Diameter = [tex]\sqrt{[(-10) - (-4)]^2+ [(-8) - (-12)]^2}=\sqrt{6^2+4^2}=2\sqrt{13}[/tex]
Radius = [tex]\sqrt{13}[/tex]
so the equation is
(x + 7)² + (y + 10)² = 13
