Question

Equation of line parallel to x- axis is

x = a

x =0

y = a

none of these



​

Answer 1

Answer:

y = a is the answer.if the line is parallel to x axis then y is a constant

Answer 2

Answer:

Let P (x,y) be any point on the x-axis. Then clearly, for all position of P we shall the same ordinate 0 or, y = 0.

Let P (x,y) be any point on the x-axis. Then clearly, for all position of P we shall the same ordinate 0 or, y = 0.Therefore, the equation of x-axis is y = a

y=a
