Explanation:

Step1: Identify independent/dependent vars

An independent variable is the one you control, and the dependent variable depends on it. Here, the total backpack weight ($b$) changes based on the gear weight ($g$).

Step2: Relate $b$ and $g$ with values

Check the pairs: $29-25=4$, $34-30=4$, $39-35=4$, $44-40=4$. So $b = g + 4$.

Answer:

1. $g$ is the independent variable, and $b$ is the dependent variable.
2. The dependent variable is always 4 more than the independent variable.
