Write four solutions for the equation: $x = 4y$

(N/A) To find the solutions for the equation $x = 4y$,we can substitute different values for $y$ and find the corresponding values of $x$.
$1$. If $y = 0$,then $x = 4(0) = 0$. So,the solution is $(0, 0)$.
$2$. If $y = 1$,then $x = 4(1) = 4$. So,the solution is $(4, 1)$.
$3$. If $y = -1$,then $x = 4(-1) = -4$. So,the solution is $(-4, -1)$.
$4$. If $y = 2$,then $x = 4(2) = 8$. So,the solution is $(8, 2)$.
