• Formula: $m = \frac\Delta Y\Delta X$ (Rise over Run).
• Economic Meaning: Marginal concepts (e.g., how much extra cost you incur for producing one more unit).

• Price = $20.
• Cost function: $TC = 50 + 10Q$.
• Identify $MC$: The slope of TC is 10. So $MC = 10$.
• Set $MC = P$: $10 = 20$.
• Wait—this implies infinite profit? (This happens with constant Marginal Cost).
• Revised Example (Quadratic Cost): $TC = 50 + Q^2$.
