Question: Suppose a multiple regression model is given by (hat{y}=3.64 x_{1}-7.99 x_{2}+30.89). An interpretation of the coefficient of (x_{1}) would be, if (x_{1}) decreases by 1

Suppose a multiple regression model is given by $\hat{y}=3.64 x_{1}-7.99 x_{2}+30.89$. An interpretation of the coefficient of $x_{1}$ would be, "if $x_{1}$ decreases by 1 unit, then the response variable will decrease by __________ units, on average, while holding $x_{2}$ constant."
