\end{figure} Figure 1 shows a sketch of the graph with equation $$y = 3 | x - 2 | + 5$$ The vertex of the graph is at the point \(P\), shown in Figure 1.
  1. Find the coordinates of \(P\).
  2. Solve the equation $$16 - 4 x = 3 | x - 2 | + 5$$ A line \(l\) has equation \(y = k x + 4\) where \(k\) is a constant.
    Given that \(l\) intersects \(y = 3 | x - 2 | + 5\) at 2 distinct points,
  3. find the range of values of \(k\).
