Answer:
x = - 7
Explanation:
What is required here is a line parallel to the y- axis and thus perpendicular to the x- axis.
The equation of a vertical line parallel to the y- axis is
x = c
Where c is the value of the x- coordinates the line passes through
The line passes through (- 7, - 2) with an x- coordinate of - 7, thus
x = - 7 ← is the equation perpendicular to the x- axis
