Answer: -40

Explanation:

Rate of change is calculated as the slope. The formula for Slope is:

S =
(x_(1)-x_(2) )/( y_(1)-y_(2))

The two points we have are when x = 3 and 6.

the points are (3, 120) and (6, 0), as we can see.

plugging into the slope formula:

S =
(120-0 )/( 3-6)

S = 120/-3

S = -40

Which hopefully makes sense, because the slope is negative, (the graph is falling).
