TS EAMCET · Maths · Straight Lines
If is the image of the point with respect to the straight line , then the length of the perpendicular drawn from to the line is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
Given, Q is the image of the point P1,1 with respect to the straight line x+y+1=0 So, point Q is by x-11=y-11=-21+1+112+12 ⇒x=-2 & y=-2 So Q≡-2,-2 Now the length of the perpendicular drawn from Q-2,-2 to the line 3x-4y+3=0 will be…
