Answer:
Since every point on the x - axis has no distance (zero distance) from the x - axis, therefore, the y - coordinate of every point lying on the x - axis is always zero. Thus, the coordinates of any point on the x - axis are of the form (x, 0), where x is the distance of the point from the y - axis.

Answer:
Answer
Let the required point be (x,0)
Since, (x,0) is equidistant from the points (−3,4) and (2,5)
∴
