Direct vs. Inverse Relationships Relationships between two variables can be direct or inverse. Direct relationship One goes up, the other goes up Represented by one variable divided by the other = constant (k) Inverse Relationship One goes up, the other goes down Represented by the variables multiplied together = constant (k)
