For the Op-amp shown above, we have $\frac{{\mathrm{V}}_{\mathrm{o}}}{{\mathrm{V}}_{\mathrm{I}}}=-\frac{{\mathrm{R}}_{\mathrm{f}}}{{\mathrm{R}}_{\mathrm{I}}}$ Comparing this circuit with the given one, We get ${\mathrm{V}}_{\mathrm{I}}=1\mathrm{V},{\mathrm{R}}_{\mathrm{f}}=10\mathrm{k}\Omega =10\times 10^3\Omega$ ${\mathrm{R}}_{\mathrm{I}}=1\mathrm{k}\Omega =1\times 10^3\Omega$ $\therefore \frac{{\mathrm{V}}_{\mathrm{o}}}{1}=-\frac{10\times 10^3}{1\times 10^3}\Rightarrow {\mathrm{V}}_{\mathrm{o}}=-10\mathrm{V}$
