# Thread: Calculus - Demand Curve

1. ## Calculus - Demand Curve

Can anyone help, I have assignment to calculate the slope of a demand curve. They have given the answer as

Q = 80 -2P

I have several values for Q and P but I cannot see how I can derive the formulae above, Is this possible? any suggestions?

2. Maybe a little extrapolation on your part would be require for people to answer you're question. Demand curve aren't standard.
