Question 1140933
{{{ ( x - h )^2 + ( y - k )^2 = r^2 }}}
( h, k ) = ( -8, 9 )
--------------------
{{{ r }}} is the distance from center to ( -1, -1 )
{{{ r^2 = ( -1 -(-8) )^2 + ( -1 - 9 )^2 }}}
{{{ r^2 = 7^2 + (-10 )^2 }}}
{{{ r^2 = 49 + 100 }}}
{{{ r^2 = 149 }}}
------------------------
{{{ ( x -( -8 ) )^2 + ( y - 9 )^2 = 149 }}}
{{{ ( x + 8 )^2 + ( y - 9 )^2 = 149 }}}
-----------------------------------------
