Final Answer :
A
Explanation :
According to the model, as x2 increases by 1 unit (holding x1 constant), y is expected to increase by 9 units. This is because the coefficient of x2 in the model is 9, indicating that for each unit increase in x2, y is expected to increase by 9 units, all other things being equal.
