Example Find the equation of the line of symmetry and the coordinates of the turning point of the graph of \ (y = x^2 - 6x + 4\).

Revise how to identify the y-intercept, turning point and axis of symmetry of a quadratic function. BBC Bitesize Scotland revision for SQA National 5 Maths.

Line graphs are drawn on two axes: the x-axis (horizontal) and the y-axis (vertical). Each axis represents a different data type, and the point at which they intersect is (0,0).
