The given circle and line are
x2 + y2+ 16x – 24y + 183 = 0______(1)
and 4x + 7y + 13 = 0______(2)
Centre and radius if the circle are
(–8, 12) and \(\sqrt{64 + 144 – 183}\) = \(\sqrt{25}\) = 5 respectively.
Equation of line C1C2 is 7x – 4y + k = 0 it passes through (–8, 12)
∴ –56 – 48 + k = 0
k = 104
Equation of line C1C2 is 7x – 4y + 104 = 0______(3)
