Introduction to graphs

Graphs are a graphical depiction of data, or relation between two or more variables. In this chapter we will learn about linear graphs, coordinates, and some applications. We will see that data becomes very easy to understand and interpret when depicted through graphs!

A series of points, discrete or continuous, forming a curve or surface, each of which represents a value of a variable make up a linear graph. It can also be called a network of lines connecting points. In this topic we will learn how to read a line graph.

How can we communicate exactly where something is in two dimensions? In this tutorial, we cover the basics of the coordinate plane and graphing points.

In this topic we will learn about visualization of sequence relationships, interpreting & graphing relationships, interpreting relationships betweens patterns on a graph, and we will do some exercises which will help us understand the use of graphs a little better!
