How do you graph a supply curve? Learn how to build and read supply curves on supply and demand graphs using real-world economics examples.
In this MRU video, we walk step-by-step through how to create a supply curve from a supply schedule and explain the two key ways economists read supply graphs.
You’ll learn:
- How to graph a supply curve from a supply schedule (data showing the quantity supplied at various prices)
- Why supply curves slope upward
- How price affects quantity supplied
- The “horizontal method” for reading supply curves: the quantity supplied at a given price
- The “vertical method” for finding minimum acceptable prices at a given quantity
Using the market for oil as an example, we show how to convert a supply schedule into a graph and how to interpret what the graph means in practice.
LEARNERS: Test your knowledge of this topic with a set of practice questions: mru.org/practice-questions/graphing-supply-curve-supply-schedule-and-how-read-supply-graph-curve-practice
TEACHERS: This topic is covered in MRU’s free Supply, Demand, and Equilibrium Unit Plan–7 days of lesson plans including videos, interactive tools, and classroom activities. These resources are always available to teachers for FREE at MRU.org: mru.io/e92
