# How do you number a coordinate grid?

## How do you number a coordinate grid?

The numbers on a coordinate grid are used to locate points. Each point can be identified by an ordered pair of numbers; that is, a number on the x-axis called an x-coordinate, and a number on the y-axis called a y-coordinate. Ordered pairs are written in parentheses (x-coordinate, y-coordinate).

## How do you pair coordinates?

An ordered pair contains the coordinates of one point in the coordinate system. A point is named by its ordered pair of the form of (x, y). The first number corresponds to the x-coordinate and the second to the y-coordinate. To graph a point, you draw a dot at the coordinates that corresponds to the ordered pair.

How are the 4 areas of a coordinate grid labeled?

The origin is at 0 on the x-axis and 0 on the y-axis. The intersecting x- and y-axes divide the coordinate plane into four sections. These four sections are called quadrants. Quadrants are named using the Roman numerals I, II, III, and IV beginning with the top right quadrant and moving counter clockwise.

### How do you read a grid coordinate?

When giving a four-figure grid reference, you should always give the eastings number first and the northings number second, very much like when giving the reading of a graph in school, where you give the x coordinate first followed by the y.

### How do you find the grid coordinates on a map?

Make sure you use the correct scale. First, locate the grid square in which the point (for example, Point A, Figure 2) is located (the point should already be plotted on the map). The number of the vertical grid line on the left (west) side of the grid square is the first and second digits of the coordinates.

What is the six digit grid coordinate for 100 meters?

On the bottom scale, the 100 meter mark nearest the vertical grid line provides the third digit, 5. On the vertical scale, the 100 meter mark nearest Point A provides the sixth digit, 3. Therefore, the six-digit grid coordinate is 115813.

#### Do you have to use imaginary lines to find coordinates?

You do not have to use imaginary lines; you can find the exact coordinates using a Coordinate Scale and Protractor. This device has two coordinating scales, 1:25,000 meters and 1:50,000 meters. Make sure you use the correct scale.

#### Why are the coordinates on my Garmin not working?

When given coordinates for a GPS position, you may find the format does not match the device’s format or that the coordinates have too many numbers. If the formatting of the coordinates does not match the format on the Garmin Device, confirm the format of the provided coordinates. Maps will often provide the position format they use.
