Given the linear equation $2x\ +\ 3y\ -\ 8\ =\ 0$, write another linear equation in two variables such that the geometrical representation of the pair so formed is:
(i) intersecting lines
Given:
Given linear equations is $2x\ +\ 3y\ -\ 8\ =\ 0$.
To do:
We have to write another linear equation in two variables such that the geometrical representation of the pair so formed is intersecting lines.
Solution:
Let another linear equation be $3x+2y-5=0$
Comparing the given pair of linear equations with the standard form of linear equations $a_1x+b_1y+c_1=0$ and $a_2x+b_2y+c_2=0$, we get,
$a_1=2, b_1=3$ and $c_1=-8$
$a_2=3, b_2=2$ and $c_2=-5$
Here,
$\frac{a_1}{a_2}=\frac{2}{3}$
$\frac{b_1}{b_2}=\frac{3}{2}$
$\frac{c_1}{c_2}=\frac{-8}{-5}=\frac{8}{5}$
$\frac{a_1}{a_2} ≠ \frac{b_1}{b_2}$
Therefore, the required line which intersects with the given line at one point is $3x+2y-5=0$.
