Answer Comparison Questions on Line Graphs

Here is a line graph to show the average temperature for every month of the year in Rome, Italy, and London, England:

Example

What is the difference in temperature between Rome and London in January?

Answer

3°C

We can see that the orange line for London is 5°C in January and the blue line for Rome is slightly above halfway between 5°C and 10°C, hence why it is 8°C and not 7°C.

8°C - 5°C = 3°C

Let's get started and have a go at answering some more comparison questions about this line graph.
