Sketch, on a single diagram, the graphs of $$\(y=\left|\frac{1}{2} x-a\right|\)$$ and $$\(y=\frac{3}{2} x-\frac{1}{2} a\)$$, where $$\(a\)$$ is a positive constant.

2.1.1 understand the meaning of |x| , sketch the graph of y = |ax + b| and use relations such as |a| = |b| a - b < x < a + b when solving equations and inequalities (Graphs of and for non-linear functions are not included.)
