Question

Choose the suitable option for coordinates of a point on y-axis

(a) Abscissa=0(b) Ordinate =0 (c) (1,1) (d) None of these​

Answer 1

Answer:

1)  Abscissa should be 0 i.e the correct option will be (a)

Step-by-step explanation:

1) if abscissa is 0 then only the coordinate of the point will become (0,y) here, since x=0 and the value of y will be anything greater than 0 so it will lie on the y axis

Answer 2

The coordinates of a point on y-axis will have Abscissa = 0

Explanation:

x-coordinate of the point is called Abscissa

y-coordinate of the point is called Ordinate

As the coordinate is on y-axis then it is on some point on y-axis and have no x-axis value because the coordinate point is not on x-axis or between x-axis and y-axis.

Extra Information:

Cartesian coordinate system =>

1. It is a plane on which we uniquely mark the point with the help of numerical coordinates.

2. There are three dimensions in a Cartesian plane having three axis lines => x-axis, y-axis and z-axis.

3. Cartesian coordinates were invented by René Descartes in 17th century.

4. The axis lines meet at a point which is called as ordered pair.

5. Ordered pair in two dimension => (2,3)  Abscissa = 2, Ordinate = 3

6. Ordered pair in three dimension => (2,3,4)
