You can use plot
plot([800 1000] ,[600 250],'--g')
Or you want insert line into image?

Here's a demo
% Define bound
%bound(1) is the x value of the bottom, left corner of the frame
%bound(2) is the y value for the same corner
%bound(3) is the width of the frame
%bound(4) is the height of the frame
bound = [.2 .1 .5 .7];
% Define grid
x = .3:.1:.6;
y = .2:.1:.7;
% Plot
cla()
xlim([0,1])
ylim([0,1])
hold on
rectangle('position', bound, 'EdgeColor','r')
% Plot vertical lines
vh = plot([x(:),x(:)],[bound(2),sum(bound([2,4]))], 'Color', [.6,.6,.6]);
% Plot horizontal lines
hh = plot([bound(1),sum(bound([1,3]))],[y(:),y(:)], 'Color', [.6,.6,.6])

My answer contains a fully functional sample with this code.
What's not working? What problems are you having? As I mentioned, if you get stuck, share the relevant sections of code (only the relvant sections that plot the grid). And carefully explain what's not working.
