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 $(1,\,\,3),\,\,3x + 2y = 3 + 6 > 0,$

for $(5, 0)$,$3 \times 5 + 0 > 0$ and

$( - 1,\,\,2)$ for $( - 1,\,\,2),\,\, - 3 + 4 > 0.$

Similarly other inequalities hold good.
