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 find the constant of proportionality?

Back

The constant of proportionality can be found by dividing one quantity by the other in a proportional relationship.

Front

What is the unit rate?

Back

The unit rate is the ratio of two measurements in which the second quantity is one unit.

Front

If y = 5x, what is the constant of proportionality?

Back

The constant of proportionality is 5.

Front

What does the point (3, 45) represent in a proportional relationship?

Back

It represents that for every 3 units of x, the value of y is 45.

Front

How can you represent a proportional relationship using a table?

Back

A table can show pairs of values (x, y) that maintain a constant ratio.

Front

What is the equation of a proportional relationship if the constant of proportionality is 4?

Back

The equation is y = 4x.

Front

What does a graph of a proportional relationship look like?

Back

A graph of a proportional relationship is a straight line that passes through the origin.

Front

If the equation is y = 10x, what is the unit rate?

Back

The unit rate is 10.

Front

What does the slope of a line in a proportional relationship represent?

Back
