Both coordinates of the point (-8, 5) are negated. Select all statements that are true about the point that results.

  1. It is the point (8, -5).Bonne réponse
  2. It lies in Quadrant IV.Bonne réponse
  3. The image lies as far right of the y-axis as the original point lay to the left of it.Bonne réponse
  4. It lies in Quadrant III, the region beside the one the original point occupies.

Explication

Negating a coordinate carries it to the other side of its own axis, so eight units left of the y-axis becomes eight units right of it and five units above the x-axis becomes five units below. That places the image in the corner diagonally opposite the one the original point occupies, so naming the region beside it treats one crossed axis as enough when both coordinates have crossed.
