Find the equation of a horizontal line passing through the point (4, – 2).

Answer : Equation of line parallel to x – axis (horizontal) is y = constant, as y – coordinate of every point on the line parallel to x – axis is – 2 i.e. constant. Therefore equation of the line parallel to x – axis and passing through (4, – 2) is y = – 2.
