Coordinates are written as (x, y) meaning the point on the x axis is written first, followed by the point on the y axis. Some children may be taught to remember this with the phrase ‘along the corridor, up the stairs’, meaning that they should follow the x axis first and then the y.

How do you write the coordinates of a point?
The coordinates are written as an “ordered pair” as shown below. The letter P is simply the name of the point and is used to distinguish it from others. The two numbers in parentheses are the x and y coordinate of the point. The first number (x) specifies how far along the x (horizontal) axis the point is.
What are the 4 coordinates?
This creates a grid with four quadrants. The four coordinate plane quadrants don’t have names but are simply known as the first quadrant, second quadrant, third quadrant, and fourth quadrant.
How do you find a coordinate?
How to find coordinates on Google Maps on the mobile app
- Open the Google Maps app on your iPhone or Android phone.
- Enter the location, or select and hold to drop a pin on the map of the location you want the coordinates for.
- Scroll down to find the coordinates.
- Tap the coordinates to copy to your phone’s clipboard.
What are the coordinates of C and D?
The coordinates of points C and D are (-6,10) and (12,-2) respectively.
How do you write quadrants?
In the first quadrant, both x and y take positive values. In the second quadrant, x is negative and y is positive. In the third quadrant, x and y are negative, and in the fourth quadrant, x is positive and y is negative.
Quadrant – Definition with Examples.
| Point | Quadrant |

What are the coordinate quadrants?
Coordinate plane quadrants are numbered I, II, III, and IV as shown on the grid below.All points in Quadrant II have a negative x-coordinate and a positive y-coordinate. All points in Quadrant III have two negative coordinates. All points in Quadrant IV have a positive x-coordinate and a negative y-coordinate.
Where is quadrant 3 on a graph?
bottom left corner
Quadrant III: The third quadrant is in the bottom left corner of the plane. Furthermore, both x and y have negative values in this quadrant. Quadrant IV: The fourth quadrant is in the bottom right corner of the plane. In this coordinate X has positive values and y has negative values.
What is coordinate in maths?
Math coordinates identify the location of a point on a graph or map. The ordered pair, (x, y) is the address of the point. The Cartesian coordinate system is the graph used to locate the point.Quadrant I has the coordinates, (x, y)
What are the coordinates of A and B respectively *?
The coordinates of points A and B are (a, 2) and (3, b) respectively, where a and b are constants. The distance AB is ✓(125) units and the gradient of the line AB is 2.
How do you find the distance between 2 coordinates?
1. Distance between two points P(x1,y1) and Q(x2,y2) is given by: d(P, Q) = √ (x2 − x1)2 + (y2 − y1)2 {Distance formula} 2. Distance of a point P(x, y) from the origin is given by d(0,P) = √ x2 + y2. 3.
What is the distance between B and D * 1 point?
Right Answer is: D
So BD = 20 – (10 + 1) = 9 Km.
When writing coordinates what comes first?
The order in which you write x- and y-coordinates in an ordered pair is very important. The x-coordinate always comes first, followed by the y-coordinate. As you can see in the coordinate grid below, the ordered pairs (3,4) and (4,3) are two different points!
Why are quadrants labeled counterclockwise?
The decision that a circle should be labelled counterclockwise was made by the ancient Babylonians long before any surviving mathematical works, so nobody really knows why it was made.
What do you call the first coordinate of a point?
A relation is a set of ordered pairs. The first coordinate (usually the x-coordinate) is called the domain and the second (usually the y-coordinate) is called the range.
How do you find the coordinates on a graph?
To identify the x-coordinate of a point on a graph, read the number on the x-axis directly above or below the point. To identify the y-coordinate of a point, read the number on the y-axis directly to the left or right of the point. Remember, to write the ordered pair using the correct order (x,y) .
What is the coordinate of a point whose ordinate is 4 and lies on Y axis?
Given ordinate of the point is 4 and the point lies on Y-axis, so its abscissa is zero. Hence, the required point is (0, 4).
What does Y coordinate mean?
Definition of y-coordinate
: a coordinate whose value is determined by measuring parallel to a y-axis specifically : ordinate.
How do you read quadrants?
The first quadrant is the upper right-hand corner of the graph, the section where both x and y are positive. The second quadrant, in the upper left-hand corner, includes negative values of x and positive values of y. The third quadrant, the lower left-hand corner, includes negative values of both x and y.
What is quadrant or axis?
Quadrant is the region enclosed by the intersection of the X-axis and the Y-axis. On the cartesian plane when the two axes, X-axis and Y-axis, intersect with each other at 90º there are four regions formed around it, and those regions are called quadrants.
What are coordinates example?
A set of values that show an exact position. On graphs it is usually a pair of numbers: the first number shows the distance along, and the second number shows the distance up or down. Example: the point (12,5) is 12 units along, and 5 units up.
