Across
  1. 3. A straight line, or an equation or expression whose graph is a straight line.
  2. 6. An image formed by plotting the solutions to an equation or inequality, or some other set of pairs of numbers, on a coordinate plane. To graph an expression containing the variable x, set y equal to that expression.
  3. 7. The most common value in a collection
  4. 9. A number that measures how steep a line is.
  5. 12. In mathematics, a rectangular arrangement of rows and columns.
  6. 13. they always have the same distance between them, so they never intersect.
  7. 16. The middle number in an ordered list of data values.
  8. 17. Going up and down.
  9. 20. A value that “lies outside”
  10. 21. A value less than zero
  11. 23. Number greater than zero
  12. 24. (such as the 2 in x2) says how many times to use the value in a multiplication.
  13. 25. Repeating pattern or shape.
  14. 26. The average of a collection of data values.
Down
  1. 1. A line that you can flip (or reflect) a graph across that results in the same graph.
  2. 2. A letter (like x) that we can use to mean different numbers at different times.
  3. 4. The set of outputs (y-coordinates) of a relation or function
  4. 5. A numerator divided by a denominator
  5. 8. The set of inputs (x-coordinates) of a relation or function.
  6. 10. An integer greater than 1 that can only be written as a product of two whole numbers in one way: as itself multiplied by 1.
  7. 11. The study of mathematical symbols and the rules for manipulating those symbols.
  8. 14. Dots in the coordinate plane representing pairs of linked measurements
  9. 15. An unordered collection of numbers or other mathematical objects, without repetitions.
  10. 18. Going from side to side
  11. 19. To rewrite an expression in a way that means the same thing but is simpler
  12. 22. An expression of the form a^d
  13. 25. The answer to an addition problem
