Linear inequalities in one variableExamples of linear inequalities
Graphing linear inequalities To graph all the numbers greater than, say, 2, make an open circle at 2, and draw an arrow to the right, like this:
To graph all the numbers less than or equal to, say, 1, make a closed circle at 1, and draw an arrow to the left, like this:
To graph all the numbers that are greater than 1 and less than or equal to 2, use a combination of open and closed circles:
