This image features a coordinate plane with several points plotted on it. The points are labeled with their coordinates, and some points are also labeled with numerical values. Here is the transcription of the coordinates and their corresponding labels: - Point (2,0) is plotted without any additional label. - Point (-2,0) is plotted without any additional label. - Point (3, -6) is plotted without any additional label. - Point (0, 0) is plotted with a line segment extending horizontally and labeled with the number 5. - Point (-3,6) is plotted without any additional label. - Point (3,-6) is plotted and labeled with the number 16. - Point (4,8) is plotted and labeled with the number 6. - Point (0,-2) is plotted and labeled with the number 7. - Point (-1,-1) is plotted without any additional label. - Point (1,-1) is plotted without any additional label. - Point (-4,-8) is plotted without any additional label. - Point (0,0) is plotted and labeled with the number 25. - Point (0,0) is plotted and labeled with the number 5. - Point (3, 6) is plotted without any additional label. - Point (9, 0) is plotted without any additional label. - Point (3, -6) is plotted and labeled with the number 16. - Point (7, 0) is plotted without any additional label. - Point (-2,0) is plotted without any additional label. - Point (3, -6) is plotted and labeled with the number 16. - Point (1,-1) is plotted without any additional label. - Point (-1,-1) is plotted without any additional label. - Point (-4,-8) is plotted without any additional label. - Point (3,-6) is plotted and labeled with the number 16. - Point (49, 0) is plotted and labeled with the number 49. - Point (-2,0) is plotted without any additional label. - Point (25, 0) is plotted and labeled with the number 25. - Point (1,-1) is plotted without any additional label. - Point (3, -6) is plotted and labeled with the number 16.
