Q. Lines $2x + y = 1$ and $2x + y = 7$ are
A) On the same side of a point $\left( 0,\frac{1}{2} \right)$
B) On the opposite side of a point $\left( 0,\frac{1}{2} \right)$
C) Same lines
D) Perpendicular lines
Explanation
(a)
Since, $2x + y = 1$ and $2x + y = 7$ are parallel lines. $(2x + y - 1)(2x + y - 7)$ is positive at point $\left( 0,\frac{1}{2} \right)$. So, lines are in the same side of a point
