The image type does not matter. Just put hold on and then call line()
hold on;
line([x1,x2], [y1,y2], 'Color', 'r', 'LineWidth', 3);
Or you can call plot() if you want
hold on;
plot([x1,x2], [y1,y2], 'r-', 'LineWidth', 3);
Or in terms of rows and columns
hold on;
line([col1,col2], [row1,row2], 'Color', 'r', 'LineWidth', 3);

I don't know why either. How could I possibly know? You haven't shared anything helpful. If you want help, post your code and the full error message (everything in red).
