Proportional Relationships Review

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 quantity is constant.

Front

How can you determine if a table of values represents a proportional relationship?

Back

A table represents a proportional relationship if the ratios of corresponding values are equivalent.

Front

What does the slope of a graph represent in a proportional relationship?

Back

The slope represents the constant rate of change between the two variables in a proportional relationship.

Front

What is the formula for finding the unit rate?

Back

The unit rate is found by dividing the quantity of one variable by the quantity of another variable, typically expressed as 'y per x'.

Front

How do you identify a linear relationship from a graph?

Back

A linear relationship can be identified from a graph if the points form a straight line.

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of y when x is zero.

Front

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

Back

Proportional relationships have a constant ratio, while non-proportional relationships do not maintain a constant ratio.

Front

How can you tell if a graph is proportional by looking at it?

Back

A graph is proportional if it passes through the origin (0,0) and forms a straight line.

Front

What is the rate of change in a linear function?

Back

The rate of change in a linear function is the ratio of the change in the y-values to the change in the x-values, often represented as 'rise over run'.

Front

What does it mean for a relationship to be linear?

Back

A linear relationship means that the change in one variable is consistent with the change in another variable, resulting in a straight line when graphed.
