The diagram shows the curve with equation \(y = 2 + 3 x - x ^ { 2 }\) and the straight lines \(l\) and \(m\).
The line \(l\) is the tangent to the curve at the point \(A\) where the curve crosses the \(y\)-axis.
- Find an equation for \(l\).
The line \(m\) is the normal to the curve at the point \(B\).
Given that \(l\) and \(m\) are parallel, - find the coordinates of \(B\).
