MCQ
The point which does not lie in the half $-$ plane $2x + 3y -12 < 0$ is:
- A$(2, 1)$
- B$(1, 2)$
- C$(-2, 3)$
- ✓$(2, 3)$
✓
Answer
Correct option: D.
$(2, 3)$
By putting the value of point $(2, 3)$ in $2x + 3y - 12,$ we get;
$2(2) + 3(3) = -12$
$= 4 + 9 - 12$
$= 13 - 12$
$= 1$ which is greater than $0$
$2(2) + 3(3) = -12$
$= 4 + 9 - 12$
$= 13 - 12$
$= 1$ which is greater than $0$
