How do you answer a inequalities on a number line?
x>2, you use an open circle above the #2 and shade to the
right. If the equation was greater than or equal to 2, you would
use a closed circle and shade to the right! Less than 2 would use
the open circle to not include 2 and you would shade all numbers to
the left of 2. Less than or equal to 2, solid circle which includes
#2 and shade all #'s to the left of 2!
