Using Graphs of Equations Worksheets
Why Do We Graph Equations? We cannot emphasize the importance of graphs, enough. They are an excellent way to define a relationship visually. The purpose of drawing a graph is to represent complex and complicated data (a data that involves too many numbers) that needs to be expressed in less space and less text. Though there are many computer programs that can generate a graph, you don't always have access to such software and programs. So why not understand the importance of graphing equation. Equations; particularly linear equations express the dependability of one variable over the other. They have two variables and where x variable is a dependent variable and y variable is the independent variable. In linear equations, one variable shows the dependency over the other which can only be represented when the equations are plotted on a graph. Graphs make a complex relationship easier and clearly defines the link between the variables if plotted correctly. However, bear in mind that if the data express a notable trend or reveals a relationship between variables, only then it is required to use a graph. If there isn't any evidence of a significant trend, a graph is not the figure of choice. A graph of an equation can tell you a great deal about the nature of the equation. These worksheets and lessons will help you better understand what you can tell about an equation from a graph of it.
