The distance, y, in centimeters, of an ant from a hole in the tree for a certain amount of time, x, in seconds, is shown in the graph:

A graph titled Motion of Ant is shown. The graph shows time in seconds on the x-axis and the Distance from Hole in centimeters on the y-axis. The scale on the x-axis is shown from 0 to 7 at increments of 1, and the scale on the y-axis is shown from 0 to 24 at increments of 4. The graph has 3 straight lines. The first line is labeled A and joins ordered pairs 0, 0 and 2, 16. The second line is labeled B and joins ordered pairs 2, 16 and 4, 16. The third line is labeled C and joins ordered pairs 4, 16 and 6, 0.
Part A: Is the graph linear or nonlinear? Explain your answer. (2 points)
Part B: In which segments is the graph increasing, decreasing, and constant? (3 points)
Part C: In your own words, describe the motion of the ant, as shown on the graph. (5 points)

Part A: The graph is a combination of linear and nonlinear segments. Segments A and C are linear, while segment B is nonlinear.

Part B:
- Segment A: The graph is increasing from 0 to 2 seconds.
- Segment B: The graph is constant from 2 to 4 seconds.
- Segment C: The graph is decreasing from 4 to 6 seconds.

Part C:
The motion of the ant can be divided into three parts based on the graph.
- In the first part (segment A), the ant is moving away from the hole in a steady, linear fashion.
- In the second part (segment B), the ant stops moving and stays at a constant distance from the hole for 2 seconds.
- In the third part (segment C), the ant starts moving back towards the hole, again in a steady, linear fashion.
