Which graft is parallel to x axis

Answer»

Answer:

Step-by-step EXPLANATION:  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.
