\mathrm{K}=\mathrm{A}_0 \mathrm{e}^{-\mathrm{Ea} / \mathrm{RT}}
Taking logarithm of both sides,
\begin{aligned} 2.303 \log \mathrm{K}=2.303 \log \mathrm{A}_0-\mathrm{Ea} / \mathrm{RT} \\ \end{aligned}

\mathrm{ \log \mathrm{K}=\log \mathrm{Ao}-\frac{E a}{2.303 R} \times \frac{1}{T}}
Clearly, it is a straight line (y=mx+c) graph between log K vs 1/T
Intercept on y-axis \mathrm{=\log \mathrm{Ao}}
