Across
- 3. The point (0,0) on a graph; the point where the y-intercept and the x-intercept cross.
- 6. The place where a line or curve crosses the y-axis
- 8. A relationship where the set of input (x) values consists of only integers in an interval
- 9. A sequence that goes from one term to the next by adding (or subtracting) the same value
- 11. The steepness of a line; can be calculated as rise over run
- 13. A number that does not exist; the square root of a negative number
- 17. y; or the variable that comes out of a function. The variable dependent on the value of the input
- 18. A real number that can be written as a ratio
- 19. When two lines have equal slopes and are next to each other; the lines never cross
- 20. When two lines have slopes that are the opposite reciprocals of each other
- 22. The r-value (shows the strength of correlation)
Down
- 1. The set of all possible input (x) values
- 2. The place where a line or curve crosses the x-axis; the zero, solution, or root of a graph
- 4. When two lines cross but the slopes aren't the opposite reciprocals of each other
- 5. x; or the variable that goes into a function
- 7. A line of a scatterplot to estimate the relationship between two sets of dada; also called a "line of best fit"
- 10. A relationship where the set of input (x) values consists of all numbers in an interval
- 12. A real number that cannot be written as a ratio
- 14. The distance a number is away from zero
- 15. a mathematical relationship that for all values of x, there exists one and only one y-value
- 16. A trend between two sets of data; can be positive, negative, or no correlation
- 21. The set of all possible output (y) values
