What is a proportional relationship?

Back

A proportional relationship is a relationship between two quantities where the ratio of one quantity to the other quantity is constant.

Front

How can you identify a proportional relationship from a table?

Back

A table represents a proportional relationship if the ratios of corresponding values are equal.

Front

What is a non-proportional relationship?

Back

A non-proportional relationship is a relationship where the ratio of one quantity to another is not constant.

Front

How can you tell if a graph represents a proportional relationship?

Back

A graph represents a proportional relationship if it is a straight line that passes through the origin (0,0).

Front

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

Back

If a graph does not pass through the origin, it indicates a non-proportional relationship.

Front

What is the equation of a proportional relationship?

Back

The equation of a proportional relationship can be expressed in the form y = kx, where k is a constant.

Front

What is the significance of the constant 'k' in a proportional relationship?

Back

The constant 'k' represents the constant of proportionality, which is the ratio of y to x.

Front

Can a linear equation represent a non-proportional relationship?

Back

Yes, a linear equation can represent a non-proportional relationship if it has a y-intercept other than zero.

Front

What is the difference between direct and inverse proportionality?

Back

Direct proportionality means that as one quantity increases, the other also increases. Inverse proportionality means that as one quantity increases, the other decreases.

How do you determine if a set of points on a graph is proportional?

Back

To determine if a set of points is proportional, check if the ratios of the y-values to the x-values are constant.
