the point lies on x axis hence its y coordinate will be zero. Its coordinates can be either (9,0) or (-9,0).
You have not mentioned 9 units from y axis on the right of origin or left of origin.
A point lies on x-axis at a distance of 9 units from y-axis. What are its coordinates? What will be the coordinates of a point if it lies on y-axis at a distance of -9 units from x-axis?
Question 10 A point lies on positive direction of x-axis at a distance of 7 units from the y-axis. What are its Coordinates, if this lies in the negative direction of y-axis at a distance of 7 units from x-axis?
