JEE | Mathematics | 2024
Let A be the point of intersection of the lines 3x+2y=14,5x−y=6and B be the point of intersection of the lines 4x+3y=8,6x+y=5. The distance of the point P(5,−2) from the line AB is
Choose the correct answer:
A.
213
B.
8
C.
25
D.
6
(Correct Answer)
Correct Answer:
6
Explanation
Point of intersection of the lines 3x+2y=14 5x−y=6 is A(2,4).
Point of intersection of the lines 4x+3y=8 6x+y=5 is B(21,2).
Eqn of line AB:
⇒y−4=2−214−2(x−2)
⇒y−4=34(x−2)
⇒3y−12=4x−8
⇒4x−3y+4=0
Distance of the point P(5,2) from the line 4x−3y+4=0 is
42+(−3)24(5)−3(−2)+4<br>=530<br>=6
