What is the significance of the origin in proportional graphs?

Back

The origin (0,0) is significant because a proportional graph must pass through it, indicating that when one quantity is zero, the other is also zero.

What is a non-proportional relationship?

Back

A non-proportional relationship is when the ratio between two quantities is not constant, and the graph does not pass through the origin.

What does it mean if a graph does not go through the origin?

Back

If a graph does not go through the origin, it indicates that there is a starting value or fixed cost, making it non-proportional.
