If the total utility curve is a straight line, it implies that the utility increases at a constant rate. Therefore, the marginal utility, which is the derivative of the total utility, would be constant, resulting in a flat line with a slope of zero.

If the Total Utility Curve Is a Straight Line, the Marginal
