Question

The abscissa of any point on y-axis is
A. 0
B. 1
C. -1
D. any number

Answer 1

The abscissa of any point on y-axis is 0.

Option (A) 0 is correct.

Extra information :  

• The x - coordinate is called abscissa and y - coordinate is called ordinate.
• x - coordinate and y - coordinate taken together are called Cartesian coordinates or coordinates of a point.
• Every point on the x-axis has zero perpendicular distance from the x-axis , so it's ordinate is zero.
• Thus, the coordinates at every point on x-axis are of the form (x,0).
• Every point on the y-axis has zero perpendicular distance from the y-axis , so it's abscissa is zero.
• Thus, the coordinates at every point on x-axis are of the form (0,y).
• The coordinates of a  point at origin is (0, 0).
