3. The line \(l\) passes through the points \(A ( - 3,0 )\) and \(B \left( \frac { 5 } { 2 } , 22 \right)\)
- Find the equation of \(l\) giving your answer in the form \(y = m x + c\) where \(m\) and \(c\) are constants.

Figure 2 shows the line \(l\) and the curve \(C\), which intersect at \(A\) and \(B\).
Given that
- \(C\) has equation \(y = 2 x ^ { 2 } + 5 x - 3\)
- the region \(R\), shown shaded in Figure 2, is bounded by \(l\) and \(C\)
- use inequalities to define \(R\).
