0. The graphs of lines x + 2y -3 = 0 and 2x + 4y + 11 = 0
- Option : C
- Explanation : (C) Slope (m) of a line ax + by + c = 0 is m = -(a/b)
∴ Slope (m1) of line x + 2y -3 = 0,
⇒ m1 =-(1/2)
and Slope (m2) of line 2x + 4y + 11 = 0
⇒ m2 = -(2/4) = -(1/2)
∵ m1 = m2 = -(1/2)
Slope of both the lines are equal
∴ Lines are parallel to each other
