If \mathrm{i} is the current in the diode and \mathrm{V} is voltage drop across it, then for given figure voltage equation is
\begin{aligned} &\mathrm{ i \times 100+V=8 \Rightarrow i=-\frac{1}{100} V+\frac{8}{100}} \\ &\mathrm{ \Rightarrow i=-(0.01) V+0.08} \end{aligned} \\ \mathrm{Thus\ the\ slope\ of\ i-V graph =\frac{1}{R_L}=0.01}
