Reading a Line Graph

The idea
A line graph shows how a measured quantity changes with another, usually with the quantity the scientist set across the bottom and the measured one up the side.
In practice
An invented graph of water temperature against heating time rises from 20°C at 0 minutes to 80°C at 6 minutes.
Where people slip
