Similarly, on a plane, Cartesian coordinates use a pair of numbers – one on the x-axis, one on the y-axis – that can be used to locate a specific point on the plane.

Find out how to solve simultaneous equations using a graph in this Bitesize KS3 maths video.

The coordinates of the turning point and the equation of the line of symmetry can be found by writing the quadratic expression in completed square form.
