## What do you mean by Coordinates of a Point?

The exact position of the points on the cartesian plane is known as the coordinates of the points. We know that there are two coordinates on the plane one is x-coordinate and the other is y-coordinate. These coordinates represent the exact position of the point on a coordinate plane. There are four quadrants in the coordinate plane first quadrant has both positive values, the second quadrant has a negative x-axis, positive y-axis, the third quadrant has both negative signs and the fourth quadrant has a positive x-axis and negative y-axis.

### Coordinates Meaning

A coordinate is a set of values that defines the accurate location of the points on a plane. Each point in a plane is assigned with some set of numbers called coordinates of a plane. There are two coordinates in the coordinate plane the first coordinate of a point is called x-coordinate and the second coordinate of a point is called y-coordinate.

**x-coordinate: **

The first number in the ordered pair is known as the x-coordinate of the point. This represents the points on the x-axis. The values on the x-axis may be positive and negative. The positive values on the x-axis will be the right side of the origin and the negative values on the x-axis will be the left side of the origin.

**y-coordinate: **

The second number in the ordered pair is known as the y-coordinate of the two-dimensional plane. The numbers on the y-axis are both positive and negative. The positive values on the y-axis will be located on the north and the negative values on the y-axis will be located on the south part of the graph.

**x-axis:** The horizontal line on the coordinate plane is known as the x-axis. The positive values on the horizontal line are indicated as the x-axis and the negative values on the horizontal line are indicated as the x’-axis.

**y-axis:** The vertical line on the coordinate plane is known as the y-axis. The positive values on the vertical line are indicated as the y-axis and the negative values on the vertical line are indicated as the y’-axis.

### How to find Coordinates of a Point?

There are some necessary steps to follow in order to find the coordinates of a point.

1. XOX’ and YOY’ are the co-ordinate axes on the graph.

2. To locate the point on the axes we need to draw a perpendicular from P on X’OX.

3. P(OT, PT) coordinate of a point is formed.

### Coordinates of a Point Examples

**Example 1.**

To find the coordinate of point P the distance of P from the x-axis is 4 units and the distance of P from the y axis is 6 units.

**Solution:**

Therefore the coordinates of a point P are (4,6).

Here a = 4 locates on x coordinate

b = 6 locates on y coordinates

**Example 2.**

To find the coordinate of point P the distance of P from the y-axis is 7 units and the distance of P from the x-axis is 7 units.

**Solution:**

Therefore the coordinates of a point P are (7,7).

Here a = 7 locates on x coordinate

b = 7 locates on y coordinates

**Example 3.**

In the adjoining figure, XOX’ and YOY’ are the coordinate axis. Find out the coordinates of point A?

**Solution:**

To locate the position of point A, draw a straight line and perpendicular line from point A to the x-axis OX, y-axis OY’.

Measure the distance between the point on the x-axis and origin, a new point on the y-axis, and origin.

The value of that point on the x-axis is 3. And the value of the point on the y-axis is -5.

So, the x coordinate is 4, y coordinate is -5.

Therefore The ordered pair is A (4, -5)

**Example 4.**

Find the coordinates of three marks in the following figure?

**Solution:**

To locate the position of point A

The ordered pair A is located in the first quadrant where both coordinates are positive.

The perpendicular distance of A from the x-axis is 4 units and the y-axis is 4 units.

So, the abscissa is 4, ordinate is 4

Therefore, the coordinates of P are (4, 4).

To locate the position of point B

The ordered pair B is also located in quadrant 1.

The perpendicular of point B from the x-axis is 0.

So, the x coordinate is 0 and the point lies on the y-axis.

The distance of B from the origin on the y-axis is 3 units.

Therefore the y coordinate is 3.

The coordinates of point Q

B (0, 3)

To locate the position of point C

Point C is located on the x-axis means its y coordinate is 0.

The distance of point C from the origin is -3 units.

So the x coordinate is -3.

Thus the Coordinates of point C (0, -3).

**Example 5.**

To find the coordinate of point P the distance of P from the y-axis is 3 units and the distance of P from the x-axis is -8 units.

**Solution:**

Therefore the coordinates of a point P are (3,-8).

Here a = 3 locates on x coordinate

b = -8 locates on y coordinates.

### FAQs on Coordinates of a Point

**1. How many coordinates are there at a point?**

The point in a two-dimensional plane has two coordinates. One is x coordinate and it is also called abscissa and the second is y coordinate and it is also called ordinate.

**2. What is meant by coordinates?**

In a plane, the set of values of a point are called coordinates.

**3. What do you mean by the coordinates of a point?**

A pair of numbers describes the position of a point in a coordinate plane by using the horizontal and vertical distances from the two reference axis they represent by (x,y) means x coordinate and y coordinate.
