10.A graph shows y plotted against x. The graph is a curve that gets closer to both axes but never touches them, and y decreases as x increases. Write down whether this graph could show direct proportion, inverse proportion, or neither.
(a)Inverse proportion
(b)Neither, because the graph does not pass through the origin
(c)Neither, because a curve cannot show a proportional relationship
(d)Direct proportion
