To convert an inequality into interval notation, solve the inequality for the variable and write the solution as an interval.

To convert an inequality into interval notation, you need to determine the range of values that satisfy the inequality. Here are the steps:

First, solve the inequality for the variable.
If the inequality includes the less than or equal to (≤) or greater than or equal to (≥) symbols, use brackets [] for inclusive values. If the inequality includes only the less than (<) or greater than (>) symbols, use parentheses () for exclusive values.
Write the solution as an interval using the variable and the symbol used in the inequality.

For example, if you have the inequality x > 2, the solution in interval notation would be (2, ∞), which means all values greater than 2.
