Draw the graph of \(y = 3x - 1\). If you recognise this as a straight line then just choose two ‘easy’ values of \(x\), work out the corresponding values of \(y\) and plot those points.

If an equation can be rearranged into the form \(y = mx + c\), then its graph will be a straight line ... can be re-written as \(y = −x + 3\)); \(3x – 4y = 12 \) can be rearranged as ...
