A ray through ( − 3 , − 2 ) reflects at ( 0 , − 2 ) from the tangent to x 2 + y 2 = 4 and the reflected ray is tangent to the circle. The incident line is J x − Ky + 26 = 0 . Find J − K .

Question

TestHub · Accepted Answer

The non-horizontal tangent through ( − 3 , − 2 ) has slope 12/5 , hence 12 x − 5 y + 26 = 0 . Thus J − K = 12 − 5 = 7 . \end{document}
