Chp 1.5 - Proportional Relationships

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 can you determine if two ratios are proportional?

Back

Two ratios are proportional if their cross products are equal.

Front

What is the definition of a ratio?

Back

A ratio is a comparison of two quantities by division.

Front

What does it mean if a graph shows a proportional relationship?

Back

If a graph shows a proportional relationship, it means that the line passes through the origin and is straight.

Front

What is the X-axis in a graph?

Back

The X-axis is the horizontal line in a graph that represents the independent variable.

Front

What is the Y-axis in a graph?

Front

What is an example of a proportional relationship?

Back

An example of a proportional relationship is the relationship between distance and time at a constant speed.

Front

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

Back

A non-proportional graph does not pass through the origin and does not maintain a constant ratio.

Front

What is the formula for finding the unit rate?

Back

The unit rate is found by dividing the two quantities, resulting in a ratio of one quantity to one unit of the other.

Front

What is a constant of proportionality?

Back

The constant of proportionality is the constant ratio in a proportional relationship, often represented by 'k'.
