Is the point (2, 1) in the solution region of x + y 3 and y < 2?

  1. Yes, it satisfies both
  2. No, because x + y = 3 is not greater than 3
  3. Yes, because x y
  4. No, because y < 2 fails
Answer

B) No, because x + y = 3 is not greater than 3

2 + 1 = 3, and 3 3 is false; points on a dashed boundary line are not included. SLO M-10-A-23 · Understanding
