Proportional or Not???

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

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

Back

A non-proportional graph does not maintain a constant ratio between the x and y values, meaning the relationship is not consistent.

Front

What is the unit rate?

Back

The unit rate is the ratio of two measurements in which the second measurement is 1 unit.

Front

How can you identify a proportional graph?

Back

A proportional graph passes through the origin (0,0) and has a straight line.

Front

What is the origin in a coordinate plane?

Back

The origin is the point where the x-axis and y-axis intersect, represented by the ordered pair (0,0).

Front

If a graph shows a straight line that does not pass through the origin, is it proportional?

Back

No, if a graph shows a straight line that does not pass through the origin, it is non-proportional.

Front

What is the unit rate for 4 cm of rainfall in 2 hours?

Back

The unit rate is 2 cm per hour.

Front

What does it mean for a relationship to be proportional?

Back

It means that as one quantity increases, the other quantity increases at a constant rate.

Front

Can a graph be both proportional and non-proportional?

Back

No, a graph is either proportional or non-proportional, not both.

Front

What is an example of a proportional relationship in real life?

Back

An example is the relationship between distance and time when traveling at a constant speed.
