im a senior in highschool taking ap calculus, ive done regressions here and there with the calculator but i was wondering how do do it without the calculator, i obviously know how to get a linear equation out of 2 points, but how is it done with more points and higher degrees?(adsbygoogle = window.adsbygoogle || []).push({});

i understand that you need 2 points for a line, 3 for a quadradic, 4 for a cubic and 5 for a quartic but i was hoping someone could show me how it is done.
