- 2. A relation between two variables that vary together.
- 4. It shows that there is no relationship between two variables
- 5. Another name for gradient.
- 7. Two or more straight coplanar lines that do not intersect.
- 12. Aquantity that does not change its value.
- 13. The measure of the steepness of a line that shows the line slants downward from left to right.
- 17. sequence in which each term (after the first one) bears a fixed ration to its previous term.
- 19. The value(s) of a variable that satisfies a given algebraic equation.
- 20. The set of all possible values for the output of the function

Down
- 1. Usually the vertical axis in a Cartesian coordinate system.
- 3. An arithmetic sequence is a sequence in which the difference between each term and e one after it is constant.
- 6. Two lines that intersect at right angles.

- 9. The set of all possible iput values for a function or relation.
- 10. Data that is plotted as points on a graph to show a possible relationship between two sets of data.
- 11. because its grapth is a straight line.
- 14. usually the horiontal axis in a Cartesian coordinate system
- 15. The value of x when a given curve crosses the x-axis.
- 16. The point where the reference axes in a coordinate system meet. The values of coordinates are normally defined as zero.
- 18. A relationship between two variables that shows one variable decreases as the other one increases.
