The point whose ordinate is 4 and which lies on y-axis is
(A) (4, 0)
(B) (0, 4)
(C) (1, 4)
(D) (4, 2)
Answer: (B) (0, 4)
Solution.
The ordinate is the y-axis (vertical) coordinate
(A) (4, 0) is lying on x-axis because here abscissa is 4 and ordinate is 0.
(B) (0, 4) is lying on y-axis because here abscissa is 0 and ordinate is 4
(C) (1, 4) lies in I quadrant because here abscissa is 1 and ordinate is 4
(D) (4, 2) lies in I quadrant because here abscissa is 4 and ordinate is 2
Therefore option (B) is correct
