The point (m, -m) lies on which of the following lines?

Answer»

The POINT (m, -m) lies on the line X = -y or x + y = 0

  • From given, we have a point (m, -m).
  • So, it's clear that the x and y COORDINATES have the same magnitude with different signs.  
  • when x coordinate is 1 then y coordinate will be -1, and the same pattern continues.
  • Therefore, the line x = -y or x + y = 0 is a line on which the point (m, -m) lies.
  • Consider the attached FIGURE for reference.
