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 6 at increments of 1, and the scale on the y-axis is shown from 0 to 18 at increments of 3. the graph has 3 straight lines. the first line is labeled k and joins ordered pairs 0, 0 and 2, 9. the second line is labeled l and joins ordered pairs 2, 9 and 5, 9. the third line is labeled m and joins ordered pairs 5, 9 and 7, 0.

part a: is the graph linear or nonlinear? explain your answer.
part b: in which segments is the graph increasing, decreasing, and constant?
part c: in your own words, describe the motion of the ant, as shown on the graph.
