# Graphs: Graphing Linear Equations

Lesson Objective
This lesson shows you the steps on plotting (i.e. graphing) the graph of linear equations.
Why Learn This?
If you are given an equation and have been asked to make sense out of it, very likely you will mentally try to visualize it.

However when the equation gets more complex, you will soon find it difficult to do it mentally. This is where coordinate plane is here to help.

With several simple steps, you will be able to draw out the equation. As a start, we will use a simple straight line equation to demonstrate this purpose.

Note that straight line equation is also called linear equation.

# Study Tips

As you watch the math video below, try to remember the following:
Tip #1
You can draw a x-y table to help you to record the coordinates of your points in an orderly manner.
Tip #2
Take note on how the coordinates of each point are calculated.
Tip #3
Only few points are used to plot the equation in this lesson. For more complicated equations, you may need more points to have a complete picture of the equation.
