Across
  1. 3. the horizonal axis of a coordinate system.
  2. 6. ratio between two variables with equivalent ratio.
  3. 9. a grid formed by two lines, the x and y, that crosses at a point called the origin
  4. 10. the ratio that defines the relation between the actual figure and its model.
  5. 14. the ratio of two different units, with a denominator on 1.
  6. 15. the point (0,0), where the x and y axis cross.
  7. 17. part of a whole where the numerator is divided by the denominator.
  8. 19. a line that shows all numbers placed in their correct positions.
  9. 20. a diagram that represents numbers as points on a plane.
Down
  1. 1. all sides and angles are the same sizes.
  2. 2. a pair of elements or numbers written in a specific and fixed order.
  3. 4. rise over sun or in Y over the change in X.
  4. 5. vertical value in a ordered pair shows distance on y axis.
  5. 7. a measure of steepness
  6. 8. horizontal value in (x,y) shows the distance of the point along the x axis.
  7. 11. y=mx+b
  8. 12. comparison between two quantities with the same units.
  9. 13. vertical axis of the coordinate system
  10. 16. a exact location in space.
  11. 18. triangles that have the same shape but different sizes.
