The rate of change for each column Is the same. Because the rate of
change is constant, the relationship is proportional.
You can express a proportional relationship by using the equation y kx,
where k represents the constant rate of change between x and y.
In this example: k 8. Write the equation as y 8x.
The table shows the number of texts Terri received in certain
