MA7 Constant of Proportionality Practice

Front

What is the constant of proportionality?

Back

The constant of proportionality is the constant factor (m) in the equation y = mx, which describes the relationship between two proportional quantities.

Front

How do you express a proportional relationship?

Back

A proportional relationship can be expressed in the form y = mx, where m is the constant of proportionality.

If y = 33x, what is the constant of proportionality?

Back

The constant of proportionality is 33.

Front

If y = 2x, what is the constant of proportionality?

Back

The constant of proportionality is 2.

What is the unit rate of eggs per cup if a recipe calls for 3/4 cup of brown sugar for every 3 eggs?

Back

The unit rate is 4 eggs per cup.

Front

Identify the constant of proportionality if m = 5.

Back

The constant of proportionality is 5.

Front

Identify the constant of proportionality if m = 1.50.

Back

The constant of proportionality is 1.50.

Front

What does it mean if two quantities are proportional?

Back

Two quantities are proportional if they maintain a constant ratio or relationship to each other.

Front

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

Back

A relationship is proportional if the ratio of y to x is constant for all pairs of values.

Front

What is the formula to find the constant of proportionality from a graph?

Back

The constant of proportionality can be found by determining the slope of the line, which is calculated as rise/run (change in y/change in x).
