Finding Linear regression equation

I have table of data

x = [65 65 62 67 69 65 61 67]

y = [105 125 110 120 140 135 95 130]

How can i find the equation y = mx+b of linear regression. I have tried so far but dont know how to find m and b ?

x = [65 65 62 67 69 65 61 67]

y = [105 125 110 120 140 135 95 130]

plot (x,y, 'r*')

lsline

% determine how many samples do we have

N= length(x)

% Fit to f(x) = b + m*x

X = [ones [N,1] x]

b = mldivide(X,y)

Answer 1

[Bruno Luong]

P=polyfit(x,y,1);
m=P(1), 
b=P(2),
% linefit = polyval(P,x)

Answer 2

[Torsten]

x = [65 65 62 67 69 65 61 67];  
y = [105 125 110 120 140 135 95 130];
X = [ones(numel(x),1),x.'];
p = X\(y.');
b = p(1)
m = p(2)
