Across
- 1. he steepness and direction of a line on a graph
- 4. intercept form the way of writing the equation of a line so that the slope (steepness) and y-intercept (where the line crosses the vertical y-axis) are immediately apparent
- 7. a fixed numerical value or a symbol representing a fixed value that doesn't change within an expression or equation.
- 9. the point where the line or curve crosses the y-axis of a graph
- 11. a single-term algebraic expression
- 14. an algebraic expression with three terms
- 16. a whole number that can be positive, negative, or zero
- 17. Equation an equation in which each term is either a constant or contains only one variable, in which each variable has an exponent of 1, and which always has a straight line as a graph
- 20. a symbol, typically a letter, used to represent an unknown numerical value in an equation or expression
Down
- 2. indicates how many times a base number or variable is multiplied by itself
- 3. a number that is multiplied by a variable
- 5. an expression consisting of one or more terms, each of which includes a variable (or variables) raised to a non-negative integer power, multiplied by a coefficient (a number)
- 6. an algebraic expression with two terms that are either added or subtracted
- 8. a rule or mapping that assigns each input value (from a set called the domain) to exactly one output value (in a set called the range)
- 10. Slope form a way to write the equation of a straight line
- 12. value its distance from zero on the number line, always resulting in a non-negative value
- 13. the set of all possible input values for which the function is defined and produces a valid output
- 15. Terms terms that have the same variables raised to the same powers
- 18. a mathematical statement that uses inequality symbols (like <, >, ≤, ≥) to compare two expressions
- 19. a mathematical statement that declares two expressions to be equal, typically involving variables
