Question: Suppose that we have assumed the straight-line regression model Y = BO + B1X1 + but the response is affected by a second variable x2

Suppose that we have assumed the straight-line regression model Y = BO + B1X1 + έ but the response is affected by a second variable x2 such that the true regression function is E(Y) = BO + B1X1 + B2X2 Is the estimator of the slope in the simple linear regression model unbiased?
