function [b0, b1]=Line1(X)
%function [b0, b1]=Line1(x,y)
%  Returns the "best fitting" line for y=b0x+b1
%Example of use.  The vectors x and y may be either rows or columns.
%x=[1 2 3]; y=[2 1 0];
% [b0, b1]=Line1(x,y);
% t=linspace(min(x),max(x));
% yhat=b0*t+b1;

x=X(:,1); y=X(:,2);

%x=x(:); y=y(:);  %Makes x, y into columns
A=[x ones(size(x))];
b=A\y;
b0=b(1); b1=b(2);
