Answer:
x = 2
Step-by-step explanation:
The given line is parallel to X-axis, so its equation is y = b (b is its intersect of Y-axis)
Therefore the perpendicular line has to be parallel to Y-axis, so its equation will be x = x₀, where x₀ is its intersect of X-axis and x-coordinate of any point it passes through.
(2, 6) ⇒ x₀ = 2
so the equation is
x = 2
