Question

If $y-4x=2$ is written in the standard form of linear equation in two variables $ax+by+c=0,$ then the value of $a$ will be .

• A. -1
• B. 2
• C. -2
• D. 4

Answer 1

The correct option is D 4

$y-4x=2$ can be rewritten as $4x-y+2=0.$

On comparing $4x-y+2=0$ with the general form of linear equation in two variables $ax+by+c=0,$ we get
$a=4,b=-1$ and $c=2.$
$\therefore$ The value $a$ is 4.
