create a line between two points on an already made plot

I have matrices x and y and make a plot with them. x=[0,...,85.8024]; (100 numbers) y=[0.8736,...,1.2157];(100 numbers) figure plot(x,y)

i want to create a line from A=(0,0.8736) to B=(85.8024,1.2157) on the same plot (red color).

Hi, I know this is a long time after the reply was written, but...

I tried this method and it drew the line between the two points, but after the second point the line veers at a seemingly random angle and then goes off into the distance. How do you draw the line so that it is just between the two points and doesn’t carry on after?

Can we create smooth line (curve) between two points?
