If the uncertanty in the slope is 1.214×1014, is the measured value of ε0 within experimental uncertainty of the accepted value? (Yes or No)

I have no idea what slope you are talking about. It sounds like a question associated with a lab experiment where you tried to measure ε0. If so, what did you measure? What is the graph? What was the slope value measured?

the value of the permittivity of free space is 1.009E11
