Let $A (- 1, 1)$ and $B (2, 3)$ be two points and $P$ be a variable point above the line $A B$ such that the area of $△ PAB$ is 10 . If the locus of $P$ is $a x + b y = 15$ , then $5 a + 2 b$ is :

Options:

Answer:

Solution:

$\frac{1}{2} h - 1 2 k 13 111 = 10 - 2 x + 3 y = 25 - \frac{6}{5} x + \frac{9}{5} y = 15 a = - \frac{6}{5}, b = \frac{9}{5} 5 a = - 6, 2 b = \frac{18}{5}$
