Down
- 1. A mathematical sentence with an equals sign
- 2. If a line contains the point (x1,y1) and has slope m, then its equation can be written as y−y1=m(x−x1)
- 5. The point on a coordinate plane where the x-axis and y-axis intersect
- 6. Two lines are perpendicular if they create a 90-degree angle
- 7. The vertical line running through the origin on a coordinate plane.
- 9. A combination of variables and numbers using arithmetic (like 6−x)

- 11. The set of outputs (y-coordinates) of a relation or function
- 14. The bottom number or expression in a fraction
- 15. A constant that a variable or expression is multiplied by
- 18. Two lines are parallel if they always have the same distance between them, so they never intersect.
