MCQ
Ordered pair that satisfy the equation x + y + 1 < 0 is:
  • A
    (0, -1)
  • B
    (-2,0)
  • C
    (2, -4)
  • D
    Both (B) and (C)
✓

Answer

  1. Both (B) and (C)

Solution:

Given inequation is x + y + 1 < 0

From option A, 0 + (-1) + 1 < 0

⇒ 0 < 0 which is false

Hence, (0, -1) is not a solution.

From option B, -2 + 0 + 1 < 0

⇒-1 < 0 which is true

Hence, (-2,0) there is a solution.

From option C, 2 - 4 + 1 < 0

⇒ -1 < 0 which is true.

Hence, (2,-4) is a solution.
