Across
- 2. a vertical line that has no slope
- 4. the y coordinate of a point where a graph intersects the y axis since the point is on the y axis its x coordinate is 0
- 8. the x- and y-axes in a number plane
- 9. the intersection of the axes on a number plane. the zero point on each axis
- 11. the x coordinate of the point where a line crosses the x axis
- 14. the horizontal number line in a number plane; the x-axis
- 16. Slope a horizontal line has a slope of 0
- 18. points that lie on the same line
- 20. lines in the same plane that do not intersect.Lines with the same slope and different y intercepts are parallel.
- 21. the first coordinate in a ordered pair of numbers; the x-axis
- 22. y=mx+b
- 23. lines that form right angles
- 25. the y coordinate in ordered pairs least to greatest
Down
