Solution
Given, point lies on the positive direction of x-axis, so its y-coordinate will be zero and it is at a distance of 7 units from the x-axis, so its coordinates are (7, 0). If it lies on negative direction of x-axis, then its x-coordinate will be zero and its distance from x-axis is 7 units, so its coordinates are (0, –7).
