Answer:
The correct option to tell whether a relationship is proportional or not is;
Step-by-step explanation:
A proportional relationship is a relationship between two variables, 'x', and 'y' such that they have equivalent ratio, such that all values of variable 'y' are given by the product of the values of the variable 'x' and a constant, 'k'
Therefore, y = k · x, from which we have;
Therefore we can use to tell whether a relationship is proportional or not proportional.
