4.1.2 Using Tables, Graphs, and Equations Proportional Rel.

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

What is the constant of proportionality?

Back

The constant of proportionality is the constant value (k) that relates two proportional quantities, often represented in the equation y = kx.

Front

How do you identify a proportional relationship from a table?

Back

A relationship is proportional if the ratios of the corresponding values are equal.

Front

What is a unit rate?

Back

A unit rate is a comparison of two different quantities when they are combined together, expressed as a quantity of one.

Front

Write the equation for a proportional relationship with a constant of proportionality of 3.

Back

y = 3x

Front

If y = 0.5x, what is the unit rate?

Back

0.5

Front

What does it mean if a table is not proportional?

Back

If a table is not proportional, it means that the ratios of the corresponding values are not constant.

Front

How can you determine the unit rate from a graph?

Back

The unit rate can be determined by finding the slope of the line in the graph.

Front

What is the slope of the line represented by the equation y = 4x?

Back

The slope is 4.

Front

If a car travels 120 miles in 2 hours, what is the unit rate?

Back

60 miles per hour.
