Plot a graph of V⁻¹ on the Vertical axis against R⁻¹ on the horizontal axis.

Draw two perpendicular axes on graph paper. Label the horizontal axis as $R^{-1}$ and the vertical axis as $V^{-1}$. Include appropriate units if they were provided (though none are given here).

For the horizontal axis ($R^{-1}$), the values range from 0.167 to 1.000. A suitable scale would be from 0 to 1.1, with major grid lines at intervals like 0.1 or 0.2.
For the vertical axis ($V^{-1}$), the values range from 0.310 to 0.434. A suitable scale would be from 0.1 to 0.5, with major grid lines at intervals like 0.05 or 0.1.

Plot each pair of ($R^{-1}$, $V^{-1}$) values on the graph.

• $(1.000, 0.434)$
• $(0.500, 0.400)$
• $(0.333, 0.385)$
• $(0.250, 0.370)$
• $(0.200, 0.310)$
• $(0.167, 0.357)$

Using a ruler, draw a straight line that best represents the trend of the plotted points. This line should pass as close as possible to all points, with roughly an equal number of points above and below the line.
