Grade 7 Module 4 Proportional Relationships

Front

Does the table represent a proportional relationship?

Back

To determine if a table represents a proportional relationship, divide y by x for each pair. If all results are the same, it is proportional.

Front

Write the equation that represents the table in the form y=kx.

Back

The equation for a proportional relationship can be written as y=kx, where k is the constant of proportionality.

Front

What is the equation for a proportional relationship?

Back

The equation for a proportional relationship is y=kx.

Front

Does the graph represent a proportional relationship?

Back

A graph represents a proportional relationship if it is a straight line that passes through the origin (0,0).

Front

Find the constant of proportionality from the table. k=_____

Back

The constant of proportionality (k) can be found by dividing y by x for any pair of values.

Front

What does the constant of proportionality (k) represent?

Back

The constant of proportionality (k) represents the ratio of y to x in a proportional relationship.

Front

If k=2, what is the equation of the proportional relationship?

Back

If k=2, the equation is y=2x.

Front

How do you identify a proportional relationship from a graph?

Back

A proportional relationship can be identified from a graph if it is a straight line that goes through the origin.

Front

What is the relationship between x and y in a proportional relationship?

Back

In a proportional relationship, as x increases, y increases at a constant rate determined by k.

Front

If y=3x, what is the value of k?

Back

If y=3x, then the constant of proportionality k is 3.
