Question

The equation of a straight line parallel to y-axis and passing through the point $(-2,5)$ is

• A. $x-2=0$
• B. $x+2=0$
• C. $y+5=0$
• D. $y-5=0$

Answer 1

Answer: (B)

$x+2=0$

$\text{The straight line parallel to y-axis is given by}x=c$

Since, it passes through $(-2,5).$

$\Rightarrow -2=c$ $\text{(on putting x=-2 in x=c})$

Therefore, the required equation of line is

$x=-2$

$\Rightarrow x+2=0$

Option B is correct.
