Question 6

The four graphs below show different relationships between $y\,$ and $x$ .

Graph E E

Graph F F

Graph G G

Graph H H

Note: Graph E represents an inverse square relationship, Graph F is a linear relationship through the origin, Graph G is an inverse relationship, and Graph H is a square relationship.

Match each graph with a statement in the table below.

Proportionality relationship	Graph letter
$y\,$ is directly proportional to $x$
$y\,$ is inversely proportional to $x$
$y\,$ is directly proportional to $x^2$
$y\,$ is inversely proportional to $x^2$
