You need to arrange the data in two columns somehow. It looks to me like the friction force is 3/10 of the normal force. That would mean that the coefficient of friction (and the slope) is 0.3, The fit is a perfect straight line. I don't know what you mean by the "quality"

You will have to draw your own graph. Make the normal force the x axis.
