Q:

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?

Accepted Solution

A:
No, because 28 and 15 have no common numbers in multiplying. and if you graph those in a line graph it is not a straight line and in order to be proportional the graph line has to pass the origin and be a straight line.
