Graphing Inequalities Flippable

How to Graph an Inequality 1). Draw a number line and label. 2). Mark the number line with an open or closed circle. 3). Shade the number line in the correct direction (left for less than, right for greater than).

The inequality is less than or equal to so we use a closed circle. The inequality is less than or equal to so we use a closed circle. 3 4 5 We shade to the left because the inequality is less than or equal to.

-4 -3 -2 The inequality is greater than so we use an open circle. The inequality is greater than so we use an open circle. -4 -3 -2 We shade to the right because the inequality is greater than.
