In A1 type the word temperature; in B1 the word kilojoules
Under these enter your data
Put the mouse pointer anywhere with in the data; use the Chart Wizard on the

When you have the chart, right click a marker in the chart; use Insert
Trendline; specify Linear trendline and in the Options check the Display
Formula
If the fit is not good, right click the trendline in the chart; use Format
Trendline and change it to a second order polynomial
