Question

$3x+2y=6\&6x+4y=18$ are ______.

• A. intersecting lines
• B. parallel lines
• C. coincident lines
• D. dependent pair of linear equations

Answer 1

The correct option is B parallel lines

For inconsistent pair of lines or parallel lines, $\frac{a_1}{a_2}=\frac{b_1}{b_2}\ne \frac{c_1}{c_2}.$

Here $\frac{3}{6}=\frac{2}{4}\ne \frac{6}{18}\to$ These are parallel lines.
