Easy

Here are four sketches representing various proportionality relationships.

Graph P P

Graph Q Q

Graph R R

Graph S S

Note: Graph P is a parabola starting at the origin, Graph Q is a hyperbola, Graph R is a straight line through the origin, and Graph S shows a curve asymptotic to both axes steeper than Q.

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 $x^2$
