This question is based on Equation of a Straight Line Chapter of M.L Aggarwal book for
ICSE Board for class 10.
Here Given :
(i) Straight line parallel to x-axis
(ii) and distance is also given
You have to find the equation of a straight line parallel to x-axis.
This is the Question Number 03 Exercise 12.1 of M.L Aggarwal.

(i) A line which is parallel to x-axis is y = a
⇒ y = 2
Hence, the equation of line parallel to x-axis which is at a distance of 2 units above it is y – 2 = 0.
(ii) A line which is parallel to x-axis is y = a
⇒ y = -3
Hence, the equation of line parallel to x-axis which is at a distance of 3 units below it is y + 3 = 0 .
