16 Here are sketches of five graphs.

Five sketch graphs with origin O. Graph A: curve from O rising more and more steeply. Graph B: straight line sloping down from a point on the y-axis. Graph C: straight line through O sloping up. Graph D: curve falling steeply then levelling off, approaching both axes. Graph E: straight line sloping up from a point on the positive y-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]
