According to Freundlich adsorption isotherm,
$\mathrm{x}/\mathrm{m}=\mathrm{k}\times {\mathrm{P}}^{\frac{1}{\mathrm{n}}}$
where, $\mathrm{x}=$ mass of gas adsorbed on mass '$\mathrm{m}$' of the absorbent at pressure $\mathrm{p}$.

$\mathrm{k}$ and $\mathrm{n}=$ constants.

Taking logarithm on both sides, we get
$\mathrm{logx}/\mathrm{m}=\mathrm{logk}+\frac{1}{\mathrm{n}}\mathrm{logp}$

This is equation of a straight line with slope of $\frac{1}{\mathrm{n}}$ and intercept of $\mathrm{logk}$.
