The slope of the total product curve is the:
A) average product.
B) slope of a line from the origin to the point.
C) marginal product.
D) marginal rate of technical substitution.

Question

Quizplus · Accepted Answer

The slope of the total product curve represents the change in total product resulting from a one-unit change in the input. This is exactly the definition of marginal product, making choice C the correct answer. A is incorrect because average product is calculated by dividing total product by the quantity of input, and does not involve the slope of the total product curve. B is incorrect because the slope of a line from the origin to the point represents the overall productivity of the input, but not the marginal productivity. D is incorrect because the marginal rate of technical substitution relates to the trade-off between two inputs, and is not directly related to the slope of the total product curve.
