A quick drawing showing the essential shape and features of a graph, which does not have to be exactly to scale.

A sketch is less exact. Mark useful features such as the intercepts, use the sign of the gradient to show the correct direction, and draw a straight line. The essential relationships must still be correct even when the axes are not precisely scaled.

A small drawing that represents the mathematical information in a question; it need not be accurately scaled unless stated.

A sketch need not be precisely to scale, but it should show the correct shape, orientation and important features such as intercepts and the turning point.

Do not assume that a sketch is drawn to scale. Use stated measurements and conventional marks, not its appearance.

A drawing that shows the essential position and shape of a graph without requiring every possible point to be plotted.

A sketch must show the correct intercept, direction and steepness.
