- 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 | |
