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])

Sorry, I didn't understand this question. What do you mean "near grid location"? And by "x and y scale" do you mean the intervals with in the grid or do you mean the scaling of each axis?
In my answer, these two lines define the placement of the grid line.
% Define grid
x = .3:.1:.6;
y = .2:.1:.7;
Assuming the image is placed in an axis where the bottom left corner of the axis is (0,0) and the top right corner is (7,9) (rough estimate from your drawing), then you can define the grid lines like this:
interval = 1; %distance between grid lines.
x = linspace(0,7,interval);
y = linspace(0,9,interval);
Give it a try. If you get stuck, share an image (or code) from the actual plot you're working with instead of a drawing.

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.
