Answer:
y = -2
Explanation:
A horizontal line passing through the point (4, -2) would have a slope of 0 because it is parallel to the x-axis, and the equation of a horizontal line passing through a point is of the form y = c, where c is a constant.
Since the line passes through the point (4, -2), the constant c in the equation y = c must be equal to -2, resulting in the equation:
y = -2
