How find the X- and Y- Intercepts of a plot?

Please tell me how to find the axis intercept of any plot. (X-intercept and Y-intercept).

for e.g.,this plot:

 x=linspace(1,10,100);
 y=randi([2 5],1,100);
 y=fliplr(sort(y));
 plot(x,y)
 grid on

That plot does not have a well defined axis intercept.

Are you asking what the intercept would be if your projected completely linearly with with the second-smallest y at x = 90 and the smallest y at x = 100 ?

Please consider the figure (plot of above code).
