MCQ
All points lying inside the triangle formed by the points $(1, 3)$, $(5,0)$ and $(-1,2)$ satisfy
- A$3x + 2y \ge 0$
- B$2x + y - 13 \le 0$
- C$2x - 3y - 12 \le 0$
- ✓All the above
✓
Answer
Correct option: D.
All the above
d
(d) For $(1,\,\,3),\,\,3x + 2y = 3 + 6 > 0,$
(d) For $(1,\,\,3),\,\,3x + 2y = 3 + 6 > 0,$
for $(5, 0)$,$3 \times 5 + 0 > 0$ and
$( - 1,\,\,2)$ for $( - 1,\,\,2),\,\, - 3 + 4 > 0.$
Similarly other inequalities hold good.
