$$x ^ { 2 } + y ^ { 2 } + D x + E y + F = 0$$
that passes through the points $( 1,9 ) , ( - 4,4 ) , ( 6,4 )$ .

• A) \(x ^ { 2 } + y ^ { 2 } - 2 x - 8 y - 8 = 0\)
• B) \(x ^ { 2 } + y ^ { 2 } - x - 4 y - 8 = 0\)
• C) \(x ^ { 2 } + y ^ { 2 } - 2 x - 8 y + 42 = 0\)
• D) \(x ^ { 2 } + y ^ { 2 } - 2 x - 8 y - 25 = 0\)
• E) \(x ^ { 2 } + y ^ { 2 } - x - 4 y - 25 = 0\)
