Study Notes
Slope Concepts
- Slope is calculated as "rise over run," indicating the change in vertical distance divided by the change in horizontal distance between two points on a line.
Slope Values
- Positive Slope indicates the line rises from left to right (e.g., 1/2, 2, 4/3).
- Negative Slope indicates the line falls from left to right (e.g., -1, -5/4, -3/2).
- Zero Slope implies a horizontal line (e.g., 0 indicates no vertical change).
- Undefined Slope suggests a vertical line, where there is no horizontal change (e.g., no slope - undefined).
Common Slope Examples
- 1/2: A positive slope, rising gently.
- -1: A negative slope, falling moderately.
- 4: A steep positive slope.
- -2: A moderately steep negative slope.
- -5/4: A moderately steep negative slope.
- 3: A positive slope that signifies a moderate rise.
Additional Slope Values
- Mixed slopes such as -25/21 and -11/10 indicate varying steepness in negative directions.
- Fractions like -1/32 and -8/11 show slight negative slopes.
- Steeper slopes can be found in values like 14 and -7, indicating sharp rises or falls.
Recap for Practice
- Students should familiarize themselves with the interpretation of slopes as both positive and negative, as well as understand the implications of zero and undefined slopes within geometrical contexts.
- Practice problems emphasize finding slopes for given points, reinforcing the concept of calculating rise over run methodically.
