The distance of the point from the line measured along the line parallel to is equal to
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
Let the equation of the line parallel to 3x-y=7 be 3x-y=λ. Since, it passes through 1,2, this point will satisfy the equation 3x-y=λ. ∴ 3-2=λ ⇒λ=1 So, the line is 3x-y=1. Now, x+y+5+3x-y=0+1⇒4x=-4⇒x=-1. Putting in x+y+5=0, we get…
