This type of curve is called a parabola and it is symmetrical. To draw the graph we need coordinates. We generate these coordinates by substituting values into the quadratic equation. A quadratic ...

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.
