Write a MATLAB script which will load an n x 2 matrix A of data and determine slope m and y intercept b of a line which minimizes the least square distance the data {A(I,1),A(I,2)} from I=1 to n and the points {A(I,1),mA(I,1)+b} from I=1 to n.
m=1;
b=1;
for i=1:10000
m=((-b*x(i))-(x(i)*y(i)))/(x(i)^2);
b=((-m*(x(i)^2))+(x(i)*y(i)))/(x(i));
end
A=[m,b];
rref (A)
I got an error message: Undefined function 'x' for input arguments of type 'double'.

You are getting this error because variables x and y are not defined in your script. I think what you intended was something like the following:
x = A(:,1);
y = A(:,2);
