Question

Write the equation of the line :

parallel to the X-axis and at a distance of 4 unit form the point (−2, 3)

Answer 1

Equation of a line parallel to the X-axis is of the form y = k (k > 0 or k < 0).

Since the line is at a distance of 4 units from the point (− 2, 3),

k = 4 + 3 = 7 or k = 3 – 4 = – 1

∴ The equation of the required line is y = 7 or y = – 1.
