This is a straightforward calculus problem it's a little more complicated because your function is kind of complicated, but that just means you have more terms to deal with, it doesn't actually change the technique. Namely, the function is f(m,b)=∑(mx_i + b - y_i) 2, the sum of the squares of the residuals. Least-squares linear regression is just a 2-variable optimization problem: find the values of (m,b) which minimize a certain function. How in the world would somebody find such an equation of other curves without a calculator?
