Front

What is the constant of proportionality?

Back

The constant of proportionality is the ratio between two proportional quantities, often represented as 'k' in the equation y = kx.

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 do you write the equation for a proportional relationship given a table of values?

Back

Identify the constant of proportionality and write the equation in the form y = kx, where k is the constant.

Front

Does this graph represent a proportional relationship? Yes or No?

Back

Yes, if the graph passes through the origin and is a straight line.

Front

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

Back

k = y/x, where y is the dependent variable and x is the independent variable.

Front

If y = 8x, what is the constant of proportionality?

Back

The constant of proportionality is 8.

Front

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

Back

It means that the relationship is not proportional.

Front

How can you tell if two quantities are proportional?

Back

If the ratio of the two quantities remains constant as their values change, they are proportional.

Front

What is an example of a proportional relationship in real life?

Back

The relationship between distance and time when traveling at a constant speed.
