To determine the range from the graph in the image, we need to focus on the values of $y$. The graph shows a line that starts at the point $(0, 180)$ and slopes down towards $(20, 0)$. This suggests that as $x$ increases from 0 to 20, the corresponding $y$-values decrease from 180 to 0.

Thus, the range of $y$ consists of all values between 0 and 180, inclusive.

The correct answer is: $0 \leq y \leq 180$

Tip: To find the range of a function from a graph, look at the vertical extent of the graph, focusing on the minimum and maximum $y$-values.
