, or, without loss of generality, the total derivative of the utility function with respect to good x, , that is, . Through any point on the indifference curve, dU/dx = 0, because U = c, where c is a constant.or example, if the MRS xy = 2, the consumer will give up 2 units of Y to obtain 1 additional unit of X. As one moves down a (standardly convex) indifference curve, the marginal rate of substitution decreases (as measured by the absolute value of the slope of the indifference curve, which decreases).
