Across
  1. 4. ratio of vertical change to horizontal change (rise over run)
  2. 7. the horizontal number line in a coordinate plane
  3. 10. a rate that is simplified so it has a denominator of 1 Example: 60 miles in 2 hourssimplifies down to 30 miles in 1 hour or 30 miles per hour.
  4. 13. an equation stating that two ratios are equivalent
  5. 16. the constant ratio or unit rate of two variable quantites (also called the constant ofvariation)
  6. 18. the rate that describes how one quantity changes in relation to another quantity
  7. 19. the relationship between two quantities that do not share a constant ratio. 10 milesper hour, 20 miles in 3 hours, 30 miles in 6 hours: They DO NOT simplify down tothe same unit rate
  8. 20. the second number listed in a coordinate pair, and it indicates the number ofmovements up or down along the y-axis
Down
  1. 1. the relationship between two variable quantities that have a constant ratio
  2. 2. a fraction that has a fraction in the numerator, denominator, or both. Keep thenumerator, rewrite the BIG fraction bar as a division symbol and then write thedenominator. Then KCF
  3. 3. two ratios (fractions) that have the same value
  4. 5. the rate of change in a linear relationship.
  5. 6. the vertical number line in a coordinate plane
  6. 8. the relationship between two quantities that have a constant ratio or unit rate. 10miles per hour, 20 miles in 2 hours, 30 miles in 3 hours. 90 miles in 9 hours. They allsimplify down to 10 miles per hour.
  7. 9. a grid that is formed when two number lines intersect and form right angles at theirzero points (origin)
  8. 11. the first number listed in a coordinate pair, and it indicates the number ofmovements right or left along the x-axis
  9. 12. the four regions created from the two perpendicular, intersecting number lines of acoordinate plane
  10. 14. the constant ratio in a direct variation (also called the constant of proportionality)
  11. 15. a pair of numbers used to graph or locate points on a coordinate graph (plane)
  12. 17. the point, (0, 0), at which two axes intersect on a coordinate plane
  13. 18. a ratio that compares two quantities with different units. Example: 30 miles per hour
