draw lines based on coordinates

Hi,

I am looking for a way to add a line to a convex function based on the coordinates.

I have a convex funtion going from x=1, y=19.99 to x=17, y=18.57. How is it possible to draw a straigt line between those two coordinates?

Thank you very much for the help!

You can try this to draw the line

x = [1 17];
y= [19.99 18.57];
line(x,y,'Color','r','LineWidth',4)

You can change the color as 'r' is for red and line width as well which is 4 for this case.

exactly what I was looking for, thanks!

Is it possible to add a circle at the starting and end Point of the line and in the middle?

Do you mean straight line will act as the diameter for the circle?

Just a small cicle at the beginning and the end of each line, as i tried to do it manually on the Picture. In Addition, also one in the middle, I'd like to Show that for a convex function the straight line is above the curved one.
