Given that \(a\) and \(b\) are positive constants,
on separate diagrams, sketch the graph with equation
\(y = | 2 x - a |\)
\(y = | 2 x - a | + b\)
Show, on each sketch, the coordinates of each point at which the graph crosses or meets the axes.
Given that the equation
$$| 2 x - a | + b = \frac { 3 } { 2 } x + 8$$
has a solution at \(x = 0\) and a solution at \(x = c\),
