- 2 units
- 5 units
- 6 units
- 65/17 units
Correct Option: D
Distance between two parallel lines 15x + 8y – 34 = 0 and 15x + 8y + 31 = 0 be d
| ⇒ d = |  | | |
| √15² + 8² |
We know that from second equation 15x + 8y = –31
| ⇒ d = | | | |
| √225 + 64 |
| = | | | |
| √289 |
| = | | | |
| 17 |
| d = | units | |
| 17 |
