Question

a line is parallel to x- axis and lies on x-axis itself then write the equation of that line​

Answer 1

Answer:

Thus, if P(x, y) is any point on AB, then y = b. Hence, the equation of a straight line parallel to x-axis at a distance b from it is y = b. The equation of x-axis is y = 0, since, x-axis is a parallel to itself at a distance 0 from it.
