The straight lines \(x+3 y-9=0\), \(4 x+5 y-1=0, p x+q y+10=0\) are concurrent, if the line \(5 x+6 y+10=0\) passes through the point
- A \((q,-p)\)
- B \((q, p)\)
- C \((p,-q)\)
- D \((p, q)\)
Answer & Solution
Correct Answer
(A) \((q,-p)\)
Step-by-step Solution
Detailed explanation
It is given that lines \(x+3 y-9=0\), \(4 x+5 y-1=0, p x+q y+10=0\) are concurrent \(\therefore \quad\left|\begin{array}{lll}1 & 3 & -9 \\ 4 & 5 & -1 \\ p & q & 10\end{array}\right|=0\)…
