Question

Any solution of the linear equation $2x+0y+9=0$ in two variables is of the form

• A. $(-9/2,m)$
• B. $(n,-9/2)$
• C. $(0,-9/2)$
• D. $(-9,0)$

Answer 1

The correct option is A

$(-9/2,m)$

Solving the above equation $2x+0y+9=0$, we obtain,

$2x+9=0$

$\Rightarrow 2x=-9$

$x=\frac{-9}{2}$

As the coefficient of y is $0$, therefore $y$ can take any value and will not affect our answer.

So the solution will be of the form $(-9/2,m)$, where $m\in R$

Hence, the option (A) is correct.
