(dumb it down and make it look like an 8th grader wrote it) The graph shows the distance, in miles, Keandra traveled from her home over a certain amount of time, in minutes.



graph with the x axis labeled time in minutes and the y axis labeled distance in miles, with a line segment from 0 comma 0 to 40 comma 50, a horizontal line segment from 40 comma 50 to 60 comma 50, a line segment from 60 comma 50 to 80 comma 100 and a line segment from 80 comma 100 to 120 comma 50

Part A: Identify the interval(s) where the graph is increasing, decreasing, and constant. (2 points)

Part B: Write a detailed description for the graph using information from Part A. (2 points)

1 answer

Part A:

  • Increasing: The graph is increasing from 0 to 40 minutes and from 60 to 80 minutes. This means Keandra was getting farther from home during these times.

  • Constant: The graph is constant from 40 to 60 minutes. Here, Keandra stayed the same distance from home.

  • Decreasing: The graph is decreasing from 80 to 120 minutes. This means Keandra was getting closer to home during this time.

Part B:

The graph shows how far Keandra traveled from her home over time. At first, from 0 to 40 minutes, she was getting farther away, moving up to 50 miles. Then, from 40 to 60 minutes, she stayed at 50 miles, like she was just hanging out in one spot. After that, from 60 to 80 minutes, she started traveling again and went up to 100 miles. Finally, from 80 to 120 minutes, she started coming back home, and her distance dropped back down to 50 miles. Overall, the graph shows that Keandra had a fun trip but then turned around to go back home.
