6 Here are sketches of five graphs.

Five sketch graphs: A is a curve from the origin getting steeper; B is a straight line with negative gradient and positive y-intercept; C is a straight line through the origin with positive gradient; D is a decreasing curve that levels off, not touching the axes; E is a straight line with positive gradient and positive y-intercept

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]
