The standard form of the equation of a circle is $(x - h)^2 + (y - k)^2 = r^2$. Substituting $h = -10$, $k = -7$, and $r = 2$, we get $(x + 10)^2 + (y + 7)^2 = 4$.

Write the Standard Form of the Equation of the Circle r=2;(h,k)=(−10,−7)\mathrm { r } = 2 ; ( \mathrm { h } , \mathrm { k } ) = ( - 10 , - 7 )r=2;(h,k)=(−10,−7)
