At the beginning of the year, adrian's savings account balance was $28. each week, he deposits another $15 into that account, and he doesn't spend any of his savings. is his savings account balance proportional to the number of weeks since the start of the year?

The given condition is not proportional.

Step-by-step explanation:

At the beginning of the year, Adrian's savings account balance was $28.

Let Adrian invests for 'x' weeks.

So, total amount will becomes :

Since 4 weeks = 1 month, it will represent a linear equation only.

Linear functions have a constant rate of change and describe a straight line on a graph. So, this is not proportional.

The given equation is in the form y = mx + b, so its linear. For the equation to be proportional, it should be in the form of y = kx.

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
