1. Check whether the given lines are parallel or perpendicular.
(i) \(\frac{x}{3} + \frac{y}{4} + \frac{1}{7} = 0\) and \(\frac{2x}{3} + \frac{y}{2} + \frac{1}{10} = 0\)
(ii) \(5x + 23y + 14 = 0\) and \(23x - 5y + 9 = 0\)
Answer:
(i) The given lines are .
(ii) The given lines are .
2. If the straight lines \(12y = -(p + 3)x + 12\), \(12x - 7y = 16\) are perpendicular then find '\(p\)'.
Answer:
The value of '\(p\)' is .
