Exploring the SSR (Sum of Squared Residuals) Function in Regression Line Derivation

Have you ever wondered why we start with the SSR function and differentiate it to derive the formula for the regression line?

Would you like to visualize what happens when we treat the SSR as a function of the slope or the y-intercept, and then set its derivative equal to zero?

Explore these concepts and deepen your understanding of the SSR function with the help of these interactive GeoGebra applets.
