New page

==Key Stage 4==
===Meaning===
When two [[variable]]s are [[proportional]] they change together by a constant amount.

===About Proportional Graphs===
: A [[Scatter Graph|scatter graph]] showing a [[proportional]] relationship has a [[linear]] [[gradient]].
: On a [[proportional]] [[Scatter Graph|scatter graph]] when one [[variable]] increases, the other increase or when one increases the other decreases.
: A [[proportional]] graph may have a non-zero [[y-intercept]].
