Root of a system equation

I did 2 plot of my system equation, and I'd got a point I which is a root of the system. I want to put the position I(x,y) of that point in the graph. How can I do this in Matlab?

You can do it using text() or xtitle() or ytitle() or title() if you want it to be marked as text. You can do it using plot() or line() if you want to draw a marker at that location.
