  1. 1. Using the Pythagorean Theorem “backwards” to determine if a triangle is a right triangle.
  2. 3. Where the graph of a line hits the y-axis
  3. 5. Pieces of data that are separated from the rest of the data on a graph
  4. 7. The relationship between a figure that has rotated, reflected, or translated and its original
  5. 8. Numbers that are not rational
  6. 9. Two angles whose sum is 180 degrees
  7. 12. The graph of this type of equation will be a line (the powers of the two variables are exactly one)
  8. 13. When you solve a linear equation and end up with something such as x = x
  9. 15. When a figure enlarges or reduces by a given scale on a coordinate plane
  10. 16. The type of table that can be used to analyze data with two (categorical) variables
  11. 17. A number to the third power
  12. 18. A variation of the Pythagorean Theorem used to determine how far apart two points are on a coordinate grid is called the Theorem
  13. 19. These kinds of lines are used (drawn) to model relationships between two sets of data. They are ALWAYS straight.
  14. 22. When you solve a linear equation and end up with something such as 4 = 7
  15. 23. Data that has two categories of data that can change (variables)
  16. 24. The kind of frequency that you can find on a two way table that relates categorical data to find patterns
  17. 25. This is the same between any two points on a straight line
  18. 26. Areas of a graph where data is grouped closely together
Down
  1. 2. The type of graph that can be used to analyze the relationship between two types of numerical data
  2. 4. When a figure “slides” on a coordinate plane
  3. 6. An equation written in the form y = kx; its graph will always go through the origin
  4. 7. Slope call also be called the rate of
  5. 10. The theorem that states that If a triangle is a right triangle, then a2 + b2 = c2.
  6. 11. A negative exponent represents repeated ___________
  7. 14. A function is a rule that assigns each input (x) to exactly one (y)
  8. 20. The relationship between a figure that has dilated and its original
  9. 21. The answer to a system of equations is the point where the graphs of the two equations
