Across
- 2. A triangle with all sides and angles equal.
- 7. A whole number that may be positive, negative, or zero.
- 8. An angle formed when two chords meet at a point on the circle.
- 9. The starting amount or value, often seen as the y‑intercept in an equation.
- 16. The longest side of a right triangle, opposite the right angle.
- 18. The point where a graph crosses the y‑axis; occurs when x = 0.
- 19. To remove brackets in an expression by distributing and simplifying.
- 21. The total distance around a two-dimensional shape.
- 23. A number that can be written as a fraction of two integers.
- 27. To predict a value outside the known data range based on a pattern or trend.
- 28. To reduce an expression to its simplest form by combining like terms or reducing fractions.
- 29. The amount of space inside a three-dimensional object, measured in cubic units.
- 31. To estimate a value between two known values in a set of data.
- 32. Non‑negative numbers without fractions or decimals (0, 1, 2, 3, …).
- 33. A decrease in value over time, often applied to items like cars or equipment.
- 34. The differences between successive y‑values in a table; used to identify linear relationships.
- 35. A simplified way to describe steps in a process or algorithm using plain language.
- 36. How often interest is calculated and added to the principal (e.g., annually, monthly).
Down
- 1. The distance around a circle.
- 3. The amount of surface inside a two-dimensional shape, measured in square units.
- 4. An increase in value over time, often used when discussing investments or property.
- 5. The initial payment made when buying something expensive like a car or house; not borrowed.
- 6. The distance from the center of a circle to any point on its edge.
- 10. A relationship that does not form a straight line on a graph; rate of change is not constant.
- 11. A letter or symbol used to represent a value that can change.
- 12. A straight line through the center connecting two points on the circle; twice the radius.
- 13. To find the value of a variable that makes an equation true.
- 14. A value that does not change.
- 15. Relationship that forms a straight‑line graph and has a constant rate of change.
- 17. An angle with its vertex at the center of a circle and sides that go to the edge.
- 20. The percent charged or earned on a loan or investment over time.
- 21. The original amount of money invested or borrowed before interest.
- 22. A measure of the steepness of a line, calculated as rise over run (Δy ÷ Δx).
- 24. To combine terms in an expression that have the same variable(s) and exponent(s).
- 25. Different fractions that represent the same part of a whole.
- 26. Anynumber on the number line, including whole numbers, fractions, and decimals.
- 30. How much one quantity changes in relation to another; in linear graphs, it's the same as slope.
