Question: model is y = Beta_0 + Beta_1 * x + e x is the non-random regressor. Can someone please help me discuss (using Gauss-Markov) how

model is y = Beta_0 + Beta_1 * x + e

x is the non-random regressor.

Can someone please help me discuss (using Gauss-Markov) how the OLS estimator of slope Beta_1 is always unbiased and how it has the smallest variance compared to any estimator of Beta_1 (regardless of what Beta_0 intercept is)
