Proportional Relationships in Tables, Graphs, & Equations

Front

What is a proportional relationship?

Back

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

Front

How do you find the constant of proportionality (k)?

Back

The constant of proportionality (k) can be found using the formula k = y/x.

Front

What does it mean if a table represents a proportional relationship?

Back

It means that the ratios of the values in the table are constant.

Front

What is the significance of the origin in a graph representing proportional relationships?

Back

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

Front

What does the point (2, 94) represent in a proportional relationship context?

Back

It represents that after 2 weeks, the total amount saved is $94.

Front

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

Back

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

Front

How can you tell if a graph is non-proportional?

Back

A graph is non-proportional if it does not pass through the origin.

Front

What is the equation of a proportional relationship?

Back

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

Front

If y = 3x, what is the constant of proportionality?

Back

The constant of proportionality is 3.

Front

What does it mean if a graph intersects the y-axis?

Back

If a graph intersects the y-axis at a point other than the origin, it indicates a non-proportional relationship.
