Step-by-step explanation:
Answer:
<em>( x + 5 )² + ( y + 4 )² = 29 </em>
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
(
,
) = ( - 5 , - 4 )
d = 2√29 ⇒ r = √29
<em>( x + 5 )² + ( y + 4 )² = 29</em>
