Question

Determine the distance between the pair of parallel lines:

8x + 15y − 34 = 0 and 8x + 15y + 31 = 0

Short/Brief Note

Solution

 The parallel lines are
8x + 15y − 34 = 0            ... (1)
8x + 15y + 31 = 0            ... (2)
Let d be the distance between the given lines.

\[\Rightarrow d = \left| \frac{- 34 - 31}{\sqrt{8^2 + {15}^2}} \right| = \frac{65}{17}\] units
