Answer:

No, his savings account balance is not proportional to the number of weeks since the start of the year

Step-by-step explanation:

At the beginning of the year, Adrian's savings account balance was $28.  Each week, he deposits another $15.

Let x be the number of weeks Adrian deposits money.

The function which models this situatuion is

[tex]y=28+15x[/tex]

This in not proportional relationship, because the graph of this function does not pass through the origin (it passes through the point (0,28) which intersects y-axis above the origin).
