The graph indicates Linda’s walk.

Question

A graph titled Position versus time for with horizontal axis time (seconds) and vertical axis position (meters). The line runs in 3 straight segments from 0 seconds 0 meters to 2 seconds 2 meters to 6 seconds 5 meters to 10 seconds 5 meters.
Which best describes the graph?

Linda started out moving, and then stopped moving after 6 seconds.
Linda started moving away from the start point, and then moved closer.
Linda never moved the entire trip.
Linda’s path results in a negative slope.

Answer 1

The best description of the graph is:

Linda started out moving, and then stopped moving after 6 seconds.

Here's why:

1. From 0 seconds to 2 seconds: Linda moves from 0 meters to 2 meters (a positive position change).
2. From 2 seconds to 6 seconds: Linda moves from 2 meters to 5 meters (she continues to move away from the start point, although the rate of movement is slowing down).
3. From 6 seconds to 10 seconds: The position remains constant at 5 meters, indicating that Linda stopped moving.

The other options do not correctly describe the graph's behavior. Linda did move during the trip, and there is no negative slope; the line segments either have a positive slope or are flat.
