Given: The parallel lines are

4x + 3y – 11 = 0 and 8x + 6y = 15

To find:

Distance between the givens parallel lines

Explanation:

The given parallel lines can be written as

4x + 3y − 11 = 0 … (1)

… (2)

Let d be the distance between the given lines.

Hence, distance between givens parallel line is
