Across
  1. 3. The natural numbers together with 0.
  2. 5. For real number x and y, y is the cube root of x, (written √2 x), if y2 = x
  3. 7. The vertical axis of a coordinate plane.
  4. 10. Two lines in a plane that never intersect
  5. 12. An integer n that can be written in the form n = k² , where k is an integer.
  6. 13. A quantity representing the power to which a given number or expression is to be raised
  7. 15. The numbers in the following never-ending sequence: 1, 2, 3, …
  8. 18. The image is a mirrored preimage; "a flip."
  9. 22. The square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides
  10. 23. The point with coordinate 0 on a number line; the point with coordinates (0, 0) in the coordinate plane
  11. 24. In the product of a constant and a variable
  12. 26. If (x1, y1) and (x2, y2) are two points on a line, then the slope of the line is the ratio m = rise/run = y/x = (y2−y1)/(x2−x1)
  13. 28. A transformation that moves a figure along a line in a plane but does not alter its size or shape.
  14. 30. A circular movement opposite to the direction of the movement of the hands of a clock
  15. 32. A rule which assigns to each member of a set of inputs, called the domain, a member of a set of outputs, called the range

Down
  1. 1. The ordered pair, (x, y), assigned to each point of the plane showing its position in relation to the x-axis and y-axis.
  2. 2. The two sides of a right triangle that form the right angle

  16. 29. Plane A plane that consists of a horizontal and vertical number line, intersecting at right angles at their origins
  17. 31. Notation: Base ten numbers written in the form a × 10^n where 1 ≤ a ≤ 10 and n is an integer.
