How To Graph the Inequality
- Draw a number line such that it includes
- Draw a point on
It would only be a closed point if the inequality is
- Draw a straight arrow pointing to the right that connects to the point at
I hope this helps a lot! :)

Explanation:
Given:
Two approaches the first step:
Multiply both sides by (-1) to make everything positive and turn the inequality sign the other way round.
Given:
As in the algebra shortcut method of changing sides of the = sign.
Move what is on the left of the
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I choose the form:
Divide both sides by 8
Subtract 6 from both sides
Divide both sides by 4
Number line 'graph'. The circle is hollow indicating 'greater than'.
Suppose it had been 'greater then or equal too'. In this case the circle would be filled in.
