SUMMARY
The discussion focuses on deriving a linear function for the selling price (p) of a product based on the quantity demanded (q). Given the points (25, 15) and (100, 10), the linear equation can be formulated using the slope-intercept form. The slope (m) is calculated as -0.05, leading to the equation p = -0.05q + 20. This function is valid for the domain where 20 ≤ q ≤ 150.
