- 5. notation function notation is a way to represent a function using symbols.
- 7. Replace a variable or expression with another value or expression in a mathematical equation or expression.
- 9. The y-intercept is the point where the graph intersects the y-axis.
- 10. rule of inequality: The golden rule of inequality states that when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality sign.
- 12. Two or more equations that share variables.
- 15. A form of writing equations, numbers, or expressions using a certain set of rules.
- 17. Find the value or values of a variable that make an equation or inequality true.
- 18. An inequality is a mathematical statement that compares two expressions and indicates that one is less than, greater than, less than or equal to, or greater than or equal to the other.
- 19. algebraic expression is a mathematical phrase that combines numbers, variables, and operations, but does not include an equals sign.
- 21. A boundary line is a line that separates different regions in a graph, particularly in the context of inequalities.
- 22. An equation is a mathematical statement that shows the equality of two expressions, typically separated by an equals sign (=).

- 1. :The slope-intercept form of a linear equation is a way to express the equation of a line.
- 2. A system of inequalities is a set of two or more inequalities that share the same variables.
- 3. A coordinate plane is a two-dimensional surface defined by two perpendicular axes.
- 4. The point where a line or curve crosses the x-axis on a graph.
- 6. Integers are a set of whole numbers that include all positive whole numbers, negative whole numbers, and zero.
- 8. The slope is a measure of the steepness or incline of a line on a graph. It is calculated as the ratio of the vertical change (rise) to the horizontal change (run) between two points on the line.
- 11. A linear inequality is a mathematical statement that compares a linear expression to a value using inequality symbols (such as <, >, ≤, or ≥).
- 13. An inverse operation is a mathematical operation that reverses the effect of another operation.
- 14. A solution set is the collection of all values that satisfy a given mathematical statement, such as an equation or inequality.
- 16. An ordered pair is a pair of numbers or elements written in a specific order, typically denoted as (x,y).
- 20. Calculate or determine the value of an expression or equation.
