Quizplus · Accepted Answer

The intercept of a regression line represents the value of the y-variable when the x-variable is equal to zero. Since we don't have any information about the x-variable, we can't determine the intercept exactly. However, we do know that the intercept will not be negative, as e to any power is always positive. Therefore, the only possible choice for the intercept is 4.6, which is answer choice C.
