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
x = 3
Just locate 3 on the number line and draw a shaded circle at 3
Example #2
x = 5
Just locate 5 on the number line and draw a shaded circle at 5
Example #3
x = 6
Just locate 6 on the number line and draw a shaded circle at 6
Example #4
x = 2
