Additive and Multiplicative Relationships Practice

Front

What is the constant of proportionality?

Back

The constant of proportionality is the unit rate that describes the relationship between two proportional quantities.

Front

What is the unit rate?

Back

The unit rate is a ratio that compares a quantity to one unit of another quantity.

Front

What is an additive relationship?

Back

An additive relationship is a relationship where a constant is added to a variable, represented by the equation y = x + b.

Front

What is a multiplicative relationship?

Back

A multiplicative relationship is a relationship where a variable is multiplied by a constant, represented by the equation y = kx.

Front

What is the equation for an additive relationship?

Back

The equation for an additive relationship is y = x + b, where b is a constant.

Front

What is the equation for a multiplicative relationship?

Back

The equation for a multiplicative relationship is y = kx, where k is a constant.

Front

How do you identify dependent and independent variables?

Back

The dependent variable is the one that depends on the independent variable. In a table, the dependent variable is usually listed in the second column.

Front

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

Back

The slope represents the constant of proportionality (k) in a multiplicative relationship.

Front

What does the y-intercept represent in an additive relationship?

Back

The y-intercept represents the constant (b) added to the variable in an additive relationship.

Front

How can you determine if a relationship is additive or multiplicative from a table?

Back

If the differences between the dependent variable values are constant, the relationship is additive. If the ratios are constant, the relationship is multiplicative.
