So the best way to answer this question is to create a table of x and y values which can be read from the above graphic.

Set X = Temperature (°C)

Y = Density (g/cm^{3})

So your table looks like

__X (Temperature)__ __ Y(Density)__

4 1.000

10 0.9997

25 0.9971

50 0.9881

100 0.9584.

Now plot the graph:

- Ensure the X-axis is Labelled Temperature (°C)
- Ensure the Y-axis is labelled Density (g/cm
^{3}) - Plot only from 4 to 100 °C as the question asks.
- The question doesn't ask for the gradient or y-intercept

Hope this helps!
