Front

What defines a proportional relationship between two variables?

Back

A proportional relationship is defined by the equation y = kx, where k is a constant.

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
