Answer:
x = 3
Explanation:
y = 2 is the equation of a horizontal line parallel to the x- axis
A line perpendicular to this then is a vertical line parallel to the y- axis with equation
x = c
where c is the value of the x- coordinates the line passes through.
We are not given a point that the line passes through so choose any value for c
x = 3 ← equation of perpendicular line
