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