The marginal rate of substitution (MRS) is calculated as the absolute value of the slope of the indifference curve at a given point. Without a specific figure provided, we cannot directly calculate or visually determine the MRS at point a. However, if the question implies that the MRS at point a is 1/2, it means that the consumer is willing to give up 1/2 of a unit of one good to obtain one additional unit of another good, keeping utility constant. This choice is selected based on the assumption that the question indirectly provides the answer.
