Graphing , , and and Writing in Interval Notation
To visualize linear inequalities and formally document their solution sets, one translates the algebraic statement into a number line graph and interval notation. In the inequality , the non-strict symbol dictates that the endpoint is included, so a bracket is placed at and the region to its right is shaded; this is written as in interval notation. For the strict inequality , the endpoint is excluded, meaning an open parenthesis is placed at , with shading to the left toward negative infinity, represented as . Similarly, for the non-strict inequality , a bracket is drawn at the boundary and the number line is shaded to the left, which translates to the interval . The process remains consistent regardless of whether the boundary value is an integer, decimal, or fraction.
