If the straight line \( \Large ax+by+c=0 \) always passes through \( \Large \left(1-2\right) \) then abc are
Correct Answer: Description for Correct answer:
Since \( \Large ax+by+c=0 \) is always passes through \( \Large \left(1-2\right) \)
\( \Large a-2b+c=0 \)
=> \( \Large 2b = a+c \)
Therefore a, b and c are in AP.
