Write the equation of the line that is parallel to x-axis and passing through the points

(i) (0, 3)

(ii) (0, - 4)

(iii) (2, – 5)

(iv) (3, 4)

Solution:

(i) We are given the co-ordinates of the Cartesian plane at (0, 3).

For the equation of the line parallel to x axis, we assume the equation as a one variable equation

independent of x containing y equal to 3.

We get the equation as y = 3

(ii) We are given the co-ordinates of the Cartesian plane at (0,- 4).

For the equation of the line parallel to x axis, we assume the equation as a one variable equation

Independent of x containing y equal to - 4.

We get the equation as y = - 4

(iii) We are given the co-ordinates of the Cartesian plane at (2, – 5).

For the equation of the line parallel to x axis, we assume the equation as a one variable equation

independent of x containing y equal to - 5.

We get the equation as y = - 5

(iv) We are given the co-ordinates of the Cartesian plane at (3, 4).

For the equation of the line parallel to x axis, we assume the equation as a one variable equation

independent of x containing y equal to 4.

We get the equation as

y = 4
