Question

At the beginning of the year, Isabel had $120 in the bank. Each week, she deposits another $20. Is her account balance proportional to the number of weeks deposit?

Answer 1

no

Explanation:

When the relation includes a point (0, c) for c ≠ 0, it is NOT a proportional relation. Here the relation includes the point (0, 120).

The balance is not proportional to the number of weeks.
