Non-Proportional Relationships

What is a non-proportional relationship?

Back

A non-proportional relationship is a type of relationship between two variables where the ratio of the variables is not constant. This means that as one variable changes, the other variable does not change at a constant rate.

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of the dependent variable (y) with respect to the independent variable (x). It indicates how steep the line is.

What is the y-intercept of a line?

Front

True or False: A non-proportional relationship passes through the origin.

Back

False. A non-proportional relationship does not necessarily pass through the origin.

Front

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

Back

In proportional relationships, the ratio of y to x is constant and the line passes through the origin. In non-proportional relationships, the ratio is not constant and the line may not pass through the origin.

What does it mean if a graph is linear?

Back

A graph is linear if it forms a straight line, indicating a constant rate of change between the two variables.

Front

What is the significance of the slope being positive or negative?

Back

A positive slope indicates that as x increases, y also increases. A negative slope indicates that as x increases, y decreases.
