It says above the graph:

An electric kettle was switched on. figure ten shows how the temperature of the water inside the kettle changed

I would think about the equation you can use to calculate power.
This will involve energy change and time taken.

Then see if you can explain how you could work out each of these things and what you could read off the graph, so as to calculate the power.

The top of the photo was cut off but it doesn’t sound as if you have to actually calculate the power.
