A) on the same side of a point \( \Large \left(0,\ \frac{1}{2}\right) \) |
B) on the Opposite side of a point \( \Large \left(0,\ \frac{1}{2}\right) \) |
C) same lines |
D) perpendicular lines. |
A) on the same side of a point \( \Large \left(0,\ \frac{1}{2}\right) \) |
Since \( \Large 2x+y=1 \ and \ 2x+y=7 \) are parallel lines \( \Large \left(2x+y-1\right) \left(2x+y-7\right) \) is positive at point \( \Large \left(0,\ \frac{1}{2}\right) \) so lines are in the same side of a point.
