The graph to the right shows a **negative linear** relationship, or an **inverse linear** relationship. It is termed negative or inverse because larger values of **P** are associated with smaller values of **Q** and smaller values of **P** are associated with larger values of **Q**.

We plot two points on the graph. When **P = 30**, the value of **Q** is only **6**, but when **P** falls to **15**, **Q** increases to **36**. As the value of **P** falls by 15 units value of **Q** rises by 30 units, so this is an **inverse** or **negative** relationship. As before, it's called a linear relationship because its graph is a straight line.
