directly proportional
Scales in tandem
Two quantities are directly proportional when they increase or decrease together at a constant rate—if one doubles, so does the other.
The relationship implies a fixed ratio between them: The cost is directly proportional to the amount purchased.
Contrasts with inversely proportional, where one quantity increases as the other decreases.
