Answer:

If two variables are directly proportional, it means that an increase in the value of one variable would cause a corresponding increase in the other variable. If they are inversely proportional, an increase in the value of one variable would cause a corresponding decrease in the other variable.

9/3 = 27/9 = 3

Therefore, the relationship is a direct variation and the function to model it is

y = 3x
