Plot a line passing through two points to the axis |

Hello: I am plotting a line in Octave by having the line run through two points.
Here are the commands:
octave:3> axis([-1,1,-1,1])
octave:4> hold on
octave:5> plot(2*rand(1,2)-1, 2*rand(1,2)-1)
The line plots fine. However, I want to extend the line such that it touches
the x and y axes. When the points in the plot() command are nearby
each other, the line is short. What I want to do is to extend the line such
that it touches the axes.
Can anyone suggest how to do this? I would appreciate it very much.
Thank you so much.
