Use the numerical value of the slope to determine the experimental value of acceleration due to gravity (g) in this experiment. 

If the correct value for g is 9.8 m/sec2, what is the accuracy, or percent error, for this experiment? 

Use the equation of the line to interpolate the period of a pendulum that is 4 meters long.
