TOTAL PRODUCT AND AVERAGE PRODUCT: A graphical connection between total product curve and average product curve stating that the slope of a line between the origin and any point on the total product curve is equal to the average product. Imagine a ray shooting out of the origin and hitting the total product curve. As this ray hits each point on the curve, remaining anchored at the origin, the slope of the ray changes. And the slope of this ray is average product.
