The coordinate plane

3. measure of a lines movement away from the x axis
4. triangles that have the same shape but different size
6. part of a whole
8. two numbers written in a certain order surrounded by parentheses, usually (1st number, 2nd number).
9. comparison between the quantities with the same unit
11. the vertical axis of a coordinate system, along which the y-coordinates are measured.
12. ratio that represents between a model
14. the point (0,0) on the coordinate plane, where the x and y-axes cross.
15. all three sides a angle are equal.
17. ratio with a denominator of 1
18. an exact location in a plane or in space that has no size or dimension, only position.

1. ratio between two varibles with a equilvent rates.
2. change in y over the change in the x or rise over run
4. equation of a line y=mx+b
5. the horizontal value in an ordered pair (x,y) that shows the distance of the point along the x-axis.
7. the horizontal axis of a coordinate system, along which x-coordinates are measured.
10. the vertical value in an ordered pair (x,y) that shows the distance of the point along the y-axis.
13. a line that shows all numbers placed in their correct positions.
16. a diagram that represents numbers as points on a plane.
