x = -5 → It's a vertical line passes through points (-5, y), where y is any real number.
A line perpendicular to the vertical line is a horizontal line.
The equation of a horizontal line is y = a, where a is any real number.
We know, the line passes through the point (1, 3.14) → x = 1 and y = 3.14.
Therefore the equation of that line is y = 3.14.
Answer: y = 3.14
