Arrhenius equation$\mathrm{K}=\mathrm{A}.{\mathrm{e}}^{-\mathrm{E}\mathrm{a}/\mathrm{R}\mathrm{T}}$
$\mathrm{l}\mathrm{n}\mathrm{K}=\mathrm{l}\mathrm{n}\mathrm{A}-\frac{\mathrm{E}\mathrm{a}}{\mathrm{R}\mathrm{T}}$
So, activation energy of reaction can be determined from the slope of lnK vs$\frac{1}{\mathrm{T}}$.

Using$\mathrm{y}=\mathrm{m}\mathrm{x}+\mathrm{c}$we can find the value of${\mathrm{E}}_{\mathrm{a}}$from slope value.
