How about you clarify it even more (so that I will know how to help you) by answering my questions? And are you now talking about text instead of a line?

Do you mean something like this:

load clown
figure
imagesc(X)
colormap(gray)
axis image

   x = 23;
   my_string =sprintf('TEXT and x = %g',x);

text(50,50, my_string,'FontSize',18,'Color',[1 1 0]) % adapt the coordinates (50,50) to your needs

If you want it in the overlay above the image but not really inthe image pixels themselves, then use line() or plot().

But if you want the line "burned into" the image, see my attached demo where it uses imline to "burn" a line into the image.
