At times, you may find trouble with coordinating graph points. But, in fact, this is relatively easy to do. When you go to higher classes, graph coordination plays a vital role in scoring good marks. Thus, you need to be thorough in coordinating graphs. Further, reading this article you will:

1. Learn the location of x-axis, y-axis and quadrants.

2. Locate a structured pair on a coordinate level surface.

3. Connect structured pairs to create a picture.

## Basic Things To Know:

First, you have to understand and know that a graph paper is essential to lay out the coordinate plane. First, understand the basic things such as what is graph, coordinates of points, and identify the x-axis and y-axis.

1. Graphs: Often, you come across the word "graphs". What exactly it is? It is nothing but a visual representation to understand the link between two variables such as x and y. Generally, it has the two axes known the x (horizontal) and y (vertical) axes. These axes match with the variables that you are relating. The point wherein these two axes intersect is termed origin and identifies as a point (0,0).

2. Coordinates of Point: A point is the fundamental relationship showed on a graph. Every point defines a pair of numbers having two coordinates. Coordinates are nothing but a set of numbers, normally used to spot the place of a point over the graph. Both x-coordinate and y-coordinate represent every single point.

3. Finding x-coordinate: The x-coordinate is a value on the graph that shows you how distant is that point from the origin on the x-axis. To find the value of x-coordinate on a graph, you need to draw a line from the point to the x-axis directly. And, the number where this line strikes the x-axis is the exact x-coordinate value.

4. Finding y-coordinate: As already mentioned every point defines two coordinates namely the x and the y coordinate. Now, as you know how to find the value of x-coordinate. Similarly, you can also find the value of y-coordinate, by drawing a line from that point to the y-axis.

The y coordinate is the value that shows you how faraway from the origin that the point is on the y-axis. To find the value of y coordinate on a graph, you may have to draw a line from the point to the y-axis directly and the number where this line smacks is the y coordinate value.

## How Do You Graph Using Coordinates?

After knowing these above-mentioned significant terms, you will be in a better position to draw and find the value of x-axis and y-axis. For instance, if your class teacher gives you an assignment to plot the point (200,300) on graph, then how will you do this? Just look at the following solution:

First, make a horizontal and vertical line. Name it as x-axis and y-axis respectively. Assign value 0 for the point where these two lines intersect. This value is known origin. Likewise assign 100, 200, 300, 400, 500 to the x-axis and y-axis, on a scale of one unit = one cm. After completing these tasks, follow these steps to plot the point (200,300).

Step 1: At the x-coordinate, draw a straight line expanding out from the value 200 on x-axis.

Step 2: Likewise, at the y-coordinate, draw a straight line expanding from the value 300 on y-axis.

Step 3: The point wherein these lines intersect is the point that you are asked to plot (200,300).

Now, you might feel how easy this is. Yes, it is very easy to do and you will not find any difficulties while doing it. Since your school may provide you with a graph paper and simply you have to assign the value and plot the required point on the graph. So, practice twice each sum before the exam and score well.
