What does a proportional relationship look like on a graph?

Back

A proportional relationship is represented by a straight line that passes through the origin (0,0).

If k = 6, what does this mean in a proportional relationship?

Back

If k = 6, it means that for every unit increase in x, y increases by 6 units, indicating a direct proportionality.

What is the significance of the origin in proportional graphs?

Back

The origin (0,0) signifies that when one quantity is zero, the other quantity is also zero, which is a key characteristic of proportional relationships.

Front

What does it mean if a relationship is not proportional?

Back

If a relationship is not proportional, it means that the ratio of the two quantities is not constant, and the graph does not form a straight line through the origin.
