This is how I would do it. First plot the lines and change the scales to log.

%Plot lines
plot([10 1 .1 10^4],[.1 1 10 10^2.5],'k')
hold on
plot([10^4 1 10^4],[1 1 10],'k')
%Make scale log
set(gca,'xScale','log')
set(gca,'yScale','log')

Then in the figure menu, Insert>Line or Insert>TextBox. You can get rid of edgecolor around box by editing it in the property inspector (Edit>Axes Properties... then select text box)

After you are satisfied with figure, File>Generate Code...
