Figure 1 shows a sketch of the parabola \(C\) with equation \(y ^ { 2 } = 8 x\). The point \(P\) lies on \(C\), where \(y > 0\), and the point \(Q\) lies on \(C\), where \(y < 0\) The line segment \(P Q\) is parallel to the \(y\)-axis.
Given that the distance \(P Q\) is 12 ,
- write down the \(y\)-coordinate of \(P\),
- find the \(x\)-coordinate of \(P\).
Figure 1 shows the point \(S\) which is the focus of \(C\).
The line \(l\) passes through the point \(P\) and the point \(S\). - Find an equation for \(l\) in the form \(a x + b y + c = 0\), where \(a\), \(b\) and \(c\) are integers.
