A point lies on the x- axis at a distance of 7 units from the y - axis. What are its coordinates ? What will be the coordinates if it lies on y -axis at a distance of −7 units from x - axis ?

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 y - axis, so its coordinate are (7,0).
If it lies on negative direction of y - axis, then its x- coordinate will be zero and its distance from x - axis is 7 units, so its coordinate are (0,−7)
