Front

What is a characteristic of a non-proportional graph?

Back

It does not maintain a constant ratio between variables.

Front

What is the slope of a proportional relationship graph?

Back

The slope is constant and equal to the ratio of the two variables.

Front

How can you identify a proportional relationship from a graph?

Back

A proportional relationship will pass through the origin and be a straight line.

Front

What is the equation of a proportional relationship?

Back

y = kx, where k is the constant of proportionality.

Front

What does it mean if a graph is non-proportional?

Back

It means that the relationship between the variables does not maintain a constant ratio.

Front

Can a non-proportional graph intersect the origin?

Back

Yes, a non-proportional graph can intersect the origin but does not maintain a constant ratio.

Front

What is the difference between proportional and non-proportional relationships?

Back

Proportional relationships have a constant ratio, while non-proportional relationships do not.
