Reflect a point in the x-axis or y-axis

Grade 8 math · Fieldbook Learning

Name ______________________ Date __________

Reflecting in the x-axis changes the sign of y. In the y-axis it changes the sign of x. In the line y = x it swaps x and y.

  1. Apply a reflection in the y-axis to the point (2, 1). What are the coordinates of the image?
  2. Apply a reflection in the y-axis to the point (−3, −3). What are the coordinates of the image?
  3. Apply a reflection in the x-axis to the point (−1, −1). What are the coordinates of the image?
  4. Apply a reflection in the y-axis to the point (−5, 6). What are the coordinates of the image?
  5. Apply a reflection in the y-axis to the point (4, 4). What are the coordinates of the image?
  6. Apply a reflection in the x-axis to the point (−6, 3). What are the coordinates of the image?
  7. Apply a reflection in the y-axis to the point (−5, 8). What are the coordinates of the image?
  8. Apply a reflection in the y-axis to the point (5, 4). What are the coordinates of the image?
  9. Apply a reflection in the y-axis to the point (−6, −7). What are the coordinates of the image?
  10. Apply a reflection in the x-axis to the point (−10, −4). What are the coordinates of the image?
  11. Apply a reflection in the y-axis to the point (2, −8). What are the coordinates of the image?
  12. Apply a reflection in the y-axis to the point (−7, 1). What are the coordinates of the image?
  13. Apply a reflection in the y-axis to the point (7, 14). What are the coordinates of the image?
  14. Apply a reflection in the x-axis to the point (5, −4). What are the coordinates of the image?
  15. Apply a reflection in the y-axis to the point (9, −3). What are the coordinates of the image?
  16. Apply a reflection in the x-axis to the point (−5, −3). What are the coordinates of the image?
  17. Apply a reflection in the x-axis to the point (16, 4). What are the coordinates of the image?
  18. Apply a reflection in the y-axis to the point (−15, 12). What are the coordinates of the image?
  19. Apply a reflection in the y-axis to the point (2, 17). What are the coordinates of the image?
  20. Apply a reflection in the y-axis to the point (1, 12). What are the coordinates of the image?
