Non Proportional Relationships

Front

What is a non-proportional relationship?

Back

A relationship where the ratio between two variables is not constant, meaning the graph does not pass through the origin.

Front

What is the y-intercept of a graph?

Back

The point where the graph intersects the y-axis, represented as (0, y).

Front

If a graph does not pass through the origin, is it proportional or non-proportional?

Back

Non-Proportional.

Front

What does it mean if a graph has a y-intercept of 0?

Back

It indicates that the relationship is proportional.

Front

What is the slope of a line?

Back

The slope is a measure of the steepness of the line, calculated as the rise over run.

Front

Can a line with a positive slope be non-proportional?

Back

Yes, if it does not pass through the origin.

Front

What is an example of a proportional relationship?

Back

The relationship between distance and time at a constant speed.

Front

What is an example of a non-proportional relationship?

Back

The relationship between the number of items purchased and the total cost when there is a fixed fee.

Front

How can you identify a proportional relationship from a table of values?

Back

If the ratio of y to x is constant for all pairs of values.

Front

What does it mean if a graph shows a constant rate of change?

Back

It indicates a linear relationship, which can be proportional or non-proportional depending on the y-intercept.
