==Key Stage 4==
===Meaning===
When two [[variable]]s are '''inversely proportional''' when one [[variable]] gets larger, the other [[variable]] gets smaller.
===About Inverse Proportionality===
: A [[Scatter Graph|scatter graph]] showing an '''inversely proportional''' relationship has a curved [[gradient]].
: On an '''inversely proportional''' [[Scatter Graph|scatter graph]] when one [[variable]] increases, the other decreases but the change is not constant.
: The [[Line of Best Fit|line of best fit]] on an '''inversely proportional''' graph will not cross either axis.
===Examples===
