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.

This answer was edited.(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 .
