hold in matlab

i have a 35 points i plot them using the matlab i need to plot them inside a jpg which is a map

The obvious method is
1) open the jpg with imread
2) plot it with image
3) type "hold on"
4) plot the points you want (with plot or scatter or whatever function you
want)

Does this give you what you want? If not, please give some more details.

You need to match the coordinates. Display the image using x and y axes
"image(x,y,my_image)". "help image" for details on that syntax. Then
plot your points/lines using the same coordinate system.

Or convert the lines/points you want to plot into pixel coordinates, so
they line up with your image.
