Final answer:
The slope represents the rate of change of pressure with respect to volume, and the y-intercept represents the pressure when volume is zero.
Step-by-step explanation:
In Excel, create a graph with pressure in atm (y-axis) and 1/volume of propane in 1/mL (x-axis). Add a trendline to the graph. The slope of the trendline represents the rate of change of pressure with respect to the volume of propane, and the y-intercept represents the pressure when the volume of propane is zero.
