Front

What is the definition of a constant ratio?

Back

A constant ratio is a fixed relationship between two quantities, meaning that as one quantity changes, the other changes at a consistent rate.

What does it mean for two quantities to be directly proportional?

Back

Two quantities are directly proportional if one quantity increases, the other quantity increases at a constant rate.

How can you identify a proportional relationship from a graph?

Back

A proportional relationship can be identified from a graph if the line passes through the origin (0,0) and is straight.
