10 Th circle \(x ^ { 2 } + y ^ { 2 } + 4 x - 2 y - \quad\) Ch s cen re \(C\) a¢ sses the id s \(A\) ad \(B\).
- State th co ida tesg \(C\).
It is \(\dot { \mathbf { g } } \dot { \mathrm { n } }\) the t th mid oin, \(D , 6 \quad A B \mathbf { h }\) s co \(\dot { \mathrm { d } } \mathbf { a }\) tes \(\left( 1 \frac { 1 } { 2 } , 1 \frac { 1 } { 2 } \right)\).
- Fid eq tin \(A B , \dot { \mathrm {~g} } \dot { \mathrm { v } }\) as wer in th fo \(\mathrm { m } y = m x + c\).
- Fidy calch atitil b \(x\)-co dia tes \(6 A\) ad \(B\).
