Across
- 2. lines with the opposite reciprocal slope
- 3. the point where a line crosses the y-axis
- 4. shifting a parent function left, right, up, down
- 6. shifting a parent function left, up, right, down, a vertical stretch or compression, and reflection.
- 11. output values (y-values) of a function
- 12. the point where a line crosses the x-axis
- 15. one x-value to every y-value
- 17. whole numbers and negative numbers; no fractions or decimals
- 18. set of pairs of input and output values
- 19. input values (x-values) of a function
- 20. a real number that can be written as a fraction
Down
- 1. when x increases, y increases; when x decreases, y decreases; y=kx
- 5. counting numbers and 0; no fractions, decimals, or negative numbers
- 7. the value of a number, regardless of its sign; distance away from 0
- 8. the steepness of a line
- 9. a real number that is not rational; cannot be written as a fraction
- 10. the simplest form in a set of functions that form a family.
- 13. where the x-axis and y-axis cross; (0,0)
- 14. a solution that does not work when substituted back into the equation
- 16. lines with the same slope
