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);

It does not seem to work,gives this error,error using line Vectors must be the same lengths ,not sure why.

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).
