A horizontal line is characterized by a constant y-value, which means that the y-coordinate does not change regardless of the x-coordinate. For a line to be horizontal, it can be expressed in the form:
y = b
where b is the constant y-value across all points on that line.
In this case, we’re given the point (2, 3). Here, the y-coordinate is 3. Therefore, the equation of the horizontal line that passes through this point is:
y = 3
This means that for any value of x, the value of y will always be 3, creating a straight horizontal line across the coordinate plane.
