MCQ
Write the correct answer in the following:
If a linear equation has solutions (-2, 2), (0, 0) and (2, -2), then it is of the form,
  • A
    y – x = 0
  • B
    x + y = 0
  • C
    -2x + y = 0
  • D
    -x + 2y = 0
✓

Answer

  1. x + y = 0
    Solution:
    Thinking Process,
  1. Firstly, consider a linear equation ax + by + c = 0.
  2. Secondly, substitute all points one by one and get three different equations.
  3. Further, simplify the three equations and then substitute the values of a, b and c in the considered equation.
