Question

On which axis do the following points lie?
(a)P(5, 0)
(b)Q(0−2)
(c)R(−4,0)
(d)S(0,5)

Answer 1

Answer:

(a) Point P lies on x-axis, since ordinate is zero.

(b) Point Q lies on y-axis, since abscissa is zero.

(c) Point R  lies on x-axis, since ordinate is zero.

(d) Point S lies on y-axis, since abscissa is zero.

Explanation:

★★ x- coordinate is called the abscissa.

★★ The y - coordinate is called ordinate.  

★★ Every point on the x-axis has no perpendicular distance from the x-axis , so its ordinate is zero. Thus , the coordinates of every point on x - axis are of the form (x,0).

 

★★ Every point on the y-axis has no perpendicular distance from the y-axis , so its abscissa is zero. Thus ,the coordinates of every point on y- axis are of the form (0,y).
