An experiment is conducted to determine the local acceleration due to gravity, \(g\), using a simple pendulum executing small-amplitude oscillations. A student records the period of oscillation \(T\) for several different string lengths \(L\). To construct a linear graph from which \(g\) can be determined from the slope \(S\) of the best-fit line, which of the following identifies the quantities to plot on the vertical and horizontal axes and the correct expression for \(g\)?
