8 Here are sketches of six graphs, labelled A to F.

Six sketch graphs through axes with origin O: A a curve from the origin getting steeper; B a straight line with positive gradient and positive y-intercept; C a straight line through the origin with positive gradient; D a straight line with negative gradient meeting both axes; E a curve decreasing towards the x-axis, not meeting either axis; F a curve from the y-axis falling ever more steeply to the x-axis

Write the letter of the graph that represents the following relationships.

(a) \(y\) is directly proportional to \(x\). [1]
(b) \(y\) is inversely proportional to \(x\). [1]
