The equation will have < or > Instead of = sign

Describe ALL possible values of x Include ALL solutions for X

If you must multiply or divide by a negative number to solve, you MUST REVERSE the inequality symbol!

-4x < 12 = Divide both sides by -4 x > -3

On a number line... Colored in circle = # is INCLUDED in answer set Non-colored circle= # is NOT included in answer set

On a graph... Dashed line = #s are NOT included in answer set Solid line = #s are INCLUDED in answer set
