Answer 1

1) element - a member of a set

2) inequality - <, <,
`\leq`,
`\geq`

3) line graph - visual tool used to illustrate solution sets

4) real number - positive or negative, rational or irrational numbers including zero

5) set - a collection or group of sets indicated by brackets, {}

6) set builder notation - a shorthand way to write a set

Explanation:

The definitions of each of the terms are as follows:

Element: In a set, each member is called its element.

Inequality: The term inequality is used to compare two values. The sign used for inequalities are <, <,
`\leq`,
`\geq`.

Line graph: It gives the solution on a number line. This is the pictorial or visual representation of the solution.

Real number: All numbers that are rational, irrational positive or negative values are called real numbers.

Set: A set is a collection of data that are enclosed in two curly brackets. The data can be numbers, sets, etc.

Set builder notation: It is a shorthand notation used to represent a given set. It defines the data inside the set using appropriate mathematical symbols.
