How can I generate a horizontal line starting at x = 0 up to a graph (see figure, red line)? The x, y coordinates are of course available for the graph.

If you have the xlimits (x0,x1) and the y-value..the required equations is y = k.
x = 1:10 ;
k = 3 ;
y = k*ones(*Size(x)) ;
plot(x,y)
Also have a look on line.

I don't understand the code. How would you elegantly solve this with the line command? In such a way that it only runs to the graph?
Thanks!

The value x1 should be freely chosen. From the point of intersection with the function (x, y) the line should run horizontally to x = 0.
