Therefore, aim to recognise the equations and graphs of quadratics, cubics, reciprocals, exponentials and circles. Sketch \(y = x^2 + x − 6\). The quadratic factorises to give \((x + 3)(x − 2 ...

If an equation can be rearranged into the form \(y = mx + c\), then its graph will be a straight line. In the above: \(x + y = 3\) can be rearranged as \(y = 3 - x\) (which can be re-written as ...
