24 These graphs show different relationships between the variables \(x\) and \(y\).

Four sketch graphs. Graph A: a straight line through the origin O. Graph B: a curve from O rising steeply then levelling off. Graph C: a curve decreasing from high on the left towards the x-axis, not touching either axis. Graph D: a straight line sloping down from the y-axis to the x-axis

Identify the graph which shows the following.

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