Graphing relationships describe how two variables are related on a graph. They are usually structured as "as one variable increases, the other increases/decreases." There are four categories of relationships: direct relationships where both variables increase, indirect relationships where one increases as the other decreases, cyclic relationships that repeat over time, and dynamic equilibrium relationships where the line eventually returns to the same place on the graph.

- 2. Graphing Relationships are… 1. …descriptions of how two variables relate to each other on a graph. 2. …usually structured “As _________ increases, __________ (increases/decreases.)” 3. …fall into 4 categories: a) Direct Relationship b) Indirect Relationship c) Cyclic Relationship d) Dynamic Equilibrium
- 3. Direct Relationship A direct relationship is when one variable increases, so does the other. They look like this:
- 4. Indirect (or Inverse) Relationship An indirect relationship is when one variable increases, the other decreases. They look like this:
- 5. Cyclic Relationship A cyclic relationship repeats itself over time. They look like this:
- 6. Dynamic Equilibrium When the line on the graph always eventually comes back to the same place. They look like this:
