Answer:
Option D
\(y=3\)
Step-by-step explanation:
we know that
The horizontal equation of a line is equal to the y-coordinate of the points through which the line passes.
In this problem we have that
The horizontal line passes through the point \((2,3)\)
The y-coordinate of the point is equal to \(3\)
therefore
the equation of the horizontal line is
\(y=3\)
