Question: The equation of straight line passing through the points (a, b, c) and (a ? b, b? c, c ? a), is
[MP PET 1994]
Options:
A) $ \frac{x-a}{a-b}=\frac{y-b}{b-c}=\frac{z-c}{c-a} $
B) $ \frac{x-a}{b}=\frac{y-b}{c}=\frac{z-c}{a} $
C) $ \frac{x-a}{a}=\frac{y-b}{b}=\frac{z-c}{c} $
D) $ \frac{x-a}{2a-b}=\frac{y-b}{2b-c}=\frac{z-c}{2c-a} $
Show Answer
Answer:
Correct Answer: B
Solution:
Required line is , $ \frac{x-a}{a-b-a}=\frac{y-b}{b-c-b}=\frac{z-c}{c-a-c} $ i.e., $ \frac{x-a}{b}=\frac{y-b}{c}=\frac{z-c}{a} $ .
