Straight Line Question 226

Question: Two straight lines passing through the point $ A(3,2) $ cut the line $ 2y=x+3 $ and x-axis perpendicularly at P and Q respectively. The equation of the line PQ is

Options:

A) $ 7x+y-21=0 $

B) $ x+7y+21=0 $

C) $ 2x+y-8=0 $

D) $ x+2y+8=0 $

Show Answer

Answer:

Correct Answer: A

Solution:

  • [a] $ \because $ Coordinate of Q are (3, 0) & it passes through PQ.
    $ \therefore $ Putting the values of $ (x=3)\And (y=0) $ is options we get. Equation of line $ PQ=7x+y-21=0 $
