Question

find the equation of a straight line which is parallel to x-axis and is at a distance of d from x axis is

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. Let P (x,y) be any point on the x-axis.
