Find the condition that the st. lines:
\( p_{1} x+q_{1} y=1, p_{2} x+q_{2} y=1 \) and \( p_{3} x+q_{3} y=1 \) may be
concurrent.
Assuming the condition is satisfied, prove that the three points \( \left(p_{1}, q_{1}\right),\left(p_{2}, q_{2}\right) \) and \( \left(p_{3}, q_{3}\right) \) are collinear.
