- 1. The point where a line crosses the x-axis.
- 2. A linear equation in the form y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.
- 4. A mathematical statement that shows two expressions are not equal.
- 6. Lines that intersect at a right angle and have slopes that are negative reciprocals of each other.
- 7. A measure of the steepness of a line, calculated as the ratio of the vertical change to the horizontal change between two points on the line.
- 8. A value that makes an equation or inequality true.
- 10. A symbol (usually a letter) that represents a number.
