The diagram shows part of the curve \(y = 2 - \frac { 18 } { 2 x + 3 }\), which crosses the \(x\)-axis at \(A\) and the \(y\)-axis at \(B\). The normal to the curve at \(A\) crosses the \(y\)-axis at \(C\).
- Show that the equation of the line \(A C\) is \(9 x + 4 y = 27\).
- Find the length of \(B C\).
