Solution

The correct option is D $y = - 7$
Consider the given points.
$(2, - 7)$

Since, this line parallel to $x - a x i s$ means that
$s l o p e (m) = 0$

We know that the equation of the line
$y - y_{1} = m (x - x_{1})$

So,
$y - (- 7) = 0 (x - 2)$

$y + 7 = 0$

$y = - 7$

Hence, this is the answer.
