You need any two points to get a striaght line. So I am selecting two random points to plot a line here.

% Random points to plot a line 
P0 = rand(1,2) ;
P1 = rand(1,2) ; 
x = [P0(1,1) P1(1,1)] ;  % x coordinates 
y = [P0(1,2) P1(1,2)] ;  % y coordinates 
% distance 
d = sqrt(sum((P0-P1).^2)) ; 

% divide into fpur equal parts 
xi = linspace(P0(1),P1(1),4) ; 
yi = interp1(x,y,xi) ;
% Mid point 
M = (P0+P1)/2 ;

% plot
plot(x,y,'b')
hold on
plot(xi,yi,'-*r')
