Question

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 line
• D. Perpendicular lines

Answer 1

The correct option is A On the same side of a point $\left(0,\frac{1}{2}\right)$

solution :-

Lines : $2x+y=1$

$2x+y=7$

At $(0,\frac{1}{2})L_1:\frac{1}{2}-1=-ve$

$L_2:\frac{1}{2}-7=-ve$

on same side of $(0,\frac{1}{2})$

as they have same signs
