Question

The equation y = 5, in two variables, can be written as:

• A. $\left(1\right)x+\left(1\right)y=5$
• B. $\left(0\right)x+\left(1\right)y=5$
• C. $\left(0\right)x+\left(0\right)y=5$
• D. $\left(1\right)x+\left(0\right)y=5$

Answer 1

The correct option is B $\left(0\right)x+\left(1\right)y=5$

Given : y=5

We know that general form of linear equation in two variables is of the form ax+by+c=0

On comparing the given equation y=5,with ax+by+c=0

We have a=0,b=1,c=-5

On substituting values of a,b,c in the given equation we get,

$\left(0\right)x+\left(1\right)y-5=0$

Therefore, $\left(0\right)x+\left(1\right)y=5$ is the correct answer.
