Four sketch graphs of y against x: Graph A a straight line through O; Graph B a decreasing curve that approaches the x-axis; Graph C a curve from O rising steeply then levelling off; Graph D a curve from O getting steeper

The graphs of \(y\) against \(x\) represent four different types of proportionality.

Match each type of proportionality in the table to the correct graph. (2)

Type of proportionalityGraph
\(y \propto x^2\)
\(y \propto x\)
\(y \propto \dfrac{1}{x}\)
\(y \propto \sqrt{x}\)
