Answer 1

Choose 2 points in the table. I chose (1, -1.5) and (5, -0.6). Set it up using the equation (m represents average rate of change):
$m = \frac{y_2-y_1}{x_2-x_1}$

It will look like this:
$m = \frac{-0.6 - (-1.5)}{5-1}$

Simplify:
$m = \frac{0.9}{4}= 0.225$

So, your answer is exactly 0.225oz/week. Hope it helps, if you have questions, ask me.
