Back

The constant of proportionality is 7.

Front

Which of the following equations represents a proportional relationship? y = 4x or y = x + 2?

Back

y = 4x represents a proportional relationship.

Front

What does it mean if an equation is non-proportional?

Back

An equation is non-proportional if it does not maintain a constant ratio between the variables.

Front

If y = 2x + 5, is this a proportional relationship?

Back

No, this is not a proportional relationship because of the +5.

Front

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

Back

If the ratio of y to x is constant for all pairs of values, the relationship is proportional.

Front

What is the graphical representation of a proportional relationship?

Back

A proportional relationship is represented by a straight line that passes through the origin (0,0).
