Proportional Graphs, Tables and Equations

Front

What is a proportional relationship?

Back

A proportional relationship is a relationship between two quantities where the ratio of one quantity to another is constant.

Front

What does it mean for a table to be proportional?

Back

A table is proportional if the ratios of the values in the table are constant and the table passes through the origin (0,0).

Front

What is a unit rate?

Back

A unit rate is a ratio that compares a quantity to one unit of another quantity, often expressed as 'per' something.

Front

How can you determine if a table is proportional?

Back

To determine if a table is proportional, check if the ratios of the values are constant and if it passes through the origin.

Front

What is the equation of a proportional relationship?

Back

The equation of a proportional relationship can be expressed in the form y = kx, where k is the constant of proportionality.

Front

What does it mean if a graph does not pass through the origin?

Back

If a graph does not pass through the origin, it indicates that the relationship is not proportional.

Front

What is the constant of proportionality?

Back

The constant of proportionality is the constant value (k) that relates the two quantities in a proportional relationship.

Front

How do you find the unit rate from a table?

Back

To find the unit rate from a table, divide the value of one quantity by the corresponding value of the other quantity.

Front

What is an example of a proportional equation?

Back

An example of a proportional equation is y = 5x, where the constant of proportionality is 5.

Front

What does it mean for a unit rate to be constant?

Back

A constant unit rate means that the ratio between the two quantities does not change regardless of the values.
