Question 4
Any solution of the linear equation 2x+0y+9=0 in two variables is of the form:


A) $(-\frac{9}{2},m)$
B) $(n,-\frac{9}{2})$
C) $(0,-\frac{9}{2})$
D) $(-9,0)$​​​​​​​

Answer 1

The answer is A.
The given linear equation is,
2x + 0y + 9 = 0
$\Rightarrow$ 2x + 9 = 0
$\Rightarrow$ 2x = -9
$\therefore x=-\frac{9}{2}$ and y can be any real number
Hence $(-\frac{9}{2},m)$ is the required form of the solution of given linear equation where m can be any real number.
