Question

The equation y = 4x + 4 describes the relationship between the quantities x and y. Are the quantities in a proportional relationship?

Answer 1

Yes, because as x grows larger so does y, that means to be in a proportional relationship.

Explanation:

Answer 2

Answer: For this to be a proportional relationship, the function would have to be y=4x. Since y=mx+b, this is not a proportional relationship because each time the value of x increases, the value for figure 0 is added on.

So, no. This is not proportional.
