Question

Write the equation as $ax+by+c=0$

• A. $x.0+1.y+2=0$
• B. $x.0+2.y-2=0$
• C. $x.0+1.y-2=0$
• D. $x.0+1.y=0$

Answer 1

The correct option is C $x.0+1.y-2=0$

Standard form of equation of a line is:

$ax+by+c=0$

Given equation of line is:

$y=2$

$\Rightarrow y-2=0$

Since $x$ is missing from the above equation which indicate that coefficient of $x$ is $0$.

$\therefore$ Given equation of line can also be written as:

$0.x+1.y-2=0$
