To find the slope of a demand curve, you need two points on the curve. The slope represents the change in quantity demanded divided by the change in price. So, choose two points (P1, Q1) and (P2, Q2) on the demand curve. Then, calculate the change in quantity demanded (ΔQ) and the change in price (ΔP). Finally, divide the change in quantity demanded by the change in price to find the slope: slope = ΔQ / ΔP.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
