From the graph given,we can say that

\mathrm{\text { Slope }=\frac{\Delta I_c}{\Delta I_B} =\frac{20\times 10^{-3}}{400\times 10^{-6}} }

              \mathrm{=50 }

\mathrm{\text { Voltage gain } =\frac{V_0}{V_i} }

\mathrm{=\frac{\Delta I_c}{\Delta I_B} \times \frac{R_L}{R_{\text {input }}}}

\mathrm{voltage \: \: gain=50\times \frac{2000}{0.5\times1000 } }

                           \mathrm{=200}

The voltage gain of the transistor is 200
