Let's say you have collected data containing information about the capacitance of two parallel plates vs. the distance between them, which is calculated theoretically according to the following inverse relationship: where: C = capacitance, d = distance, A = area of one plate, = electric permittivity of free space You want to model the data as a straight line so you can calculate the value of . To do this, what variable should you plot on the Y and X axes such that the data forms a linear relationship
