Graphing equalities
Graphing equalities is probably is the easiest thing to do.
If you are familiar with a number line, you should have no problems.
An equation is a mathematical sentence with an equal sign.
Equations such as x = 5 and x = 2 are examples of equalities.
Equalities such as x = 2 are what we will be dealing with.
The procedure to follow to graph x = 5 and x = 2 is simple and straightforward.
You must know how to graph equalities before learning how to graph linear inequalities.
Simply locate on the number line the value of x or any other variables used for the equality and make a shaded circle at the value of x
Example #1
Here is how to graph x = 3
Just locate 3 on the number line and draw a shaded circle at 3.
Example #2
Here is how to graph x = 5
Just locate 5 on the number line and draw a shaded circle at 5.
Example #3
Here is how to graph x = 6
Just locate 6 on the number line and draw a shaded circle at 6.
Example #4
Here is how to graph x = 2
