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 a table is proportional?

Back

A table is proportional if the ratios of the corresponding values are equal.

Front

What does slope represent in a graph?

Back

Slope represents the rate of change between two variables in a graph, indicating how much one variable changes for a unit change in another.

Front

What is the formula for calculating slope?

Back

Slope (m) = (change in y) / (change in x) = (y2 - y1) / (x2 - x1).

Front

What does a slope of 1/4 indicate?

Back

A slope of 1/4 indicates that for every 4 units you move horizontally, you move 1 unit vertically.

Front

What does a negative slope indicate?

Back

A negative slope indicates that as one variable increases, the other variable decreases.

Front

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

Back

Proportional graphs pass through the origin and have a constant slope, while non-proportional graphs do not pass through the origin and have varying slopes.

Front

How can you identify a non-proportional relationship in a table?

Back

A non-proportional relationship can be identified if the ratios of the corresponding values are not constant.

Front

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

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

If a graph is non-proportional, it means that the relationship between the variables does not maintain a constant ratio.
