Inequalities
Inequality - a mathematical statement comparing expressions that may not be equal
Graphing linear inequalities
When creating a number line, start by placing the boundary point in the middle of the line
While the next three numbers on each side of that #
Draw a circle at the boundary point
Shade the circle if the boundary point is part of the solution
Don't shade the circle if the solution begins at the boundary point but does not include it

Key Ideas
The solution to an inequality is the value that makes the inequality
You can solve an inequality involving addition, subtraction, multiplication and division by isolating the variable.
