Find the gradient of the straight line with equation  .

The diagram shows an octagon

and are lines of symmetry.

Work out the coordinates of point .

A straight line is drawn on the centimetre grid.

Fay assumes that the scale is 1 cm represents 1 unit.

Use her assumption to work out the gradient of the line.

In fact, the scale is 1 cm represents 2 units.
