4. Linear Equations in Two Variables
medium
Write four solutions for equations : $x=4 y$
Option A
Option B
Option C
Option D
Solution
When $x=0$, $4y=0$ $\Rightarrow y=0$
$\therefore$ Solution is $(0,\,0)$.
When $x=1$, $4y=1$ $\Rightarrow y =\frac{1}{4}$
$\therefore$ Solution is $\left(1, \frac{1}{4}\right)$
When $x=4$, $4y=4$ $\Rightarrow y =\frac{4}{4}=1$
$\therefore$ Solution is $(4,\,1)$.
When $x=-4$, $4y=-4$ $\Rightarrow y =\frac{-4}{4}=-1$
$\therefore$ Solution is $(-4,\,-1)$.
