MATLAB: I would like to do the same thing as the following code but with only one line that gets drawn at different angles… Any ideas

code

 %Start of code
n=100;
x0=3;
y0=4;
x=linspace(0,20,n);
y=[];
for i=1:n;
  phi(i)=45+3*randn;
  m(i)=tand(phi(i));
  c(i)= y0-m(i)*x0;
y(i,:)=m(i)*x+c(i);
plot(x,y(i,:))
hold on
end

I am not certain what you want.
Try this:
n=100;
x0=3;
y0=4;
x=linspace(0,20,n);
y=[];
for i=1:n;
    phi(i)=45+3*randn;
    m(i)=tand(phi(i));
    c(i)= y0-m(i)*x0;
    y(i,:)=m(i)*x+c(i);
    plot(x,y(i,:))
    axis([0  20    0  25])
    refreshdata
    drawnow
end
