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)

Solution:

The given linear equation is

2x + 0y + 9 = 0

We can write it as

2x + 9 = 0

2x = -9

x = -9/2

As the y coefficient is 0 it can take any value and will not affect the answer.

Therefore, the linear equation in two variables is of the form (-9/2, m).

✦ Try This: Any solution of the linear equation 3x + 0y + 4 = 0 in two variables is of the form a. (-4/3, m), b. (n, -4/3), c. (0, -4/3), d. (-4, 0)

The given linear equation is

3x + 0y + 4 = 0

We can write it as

3x + 4 = 0

3x = -4

x = -4/3

As the y coefficient is 0 it can take any value and will not affect the answer.

Therefore, the linear equation in two variables is of the form (-4/3, m).
