Begins with guided notes that describe the meaning of slope, and how to calculate slope. Introduces students to slope as the rate of change, and a ratio of the change in the y-value to the change in the x-value. Includes many real-life examples so that students develop a deep understanding of the meaning of slope. After completing this packet students will understand:
- Slope is a ratio that describes how fast or slow, and in which direction something changes.
- The steeper the line, or the farther away from zero the slope is, the faster the change is; whether it is a positive or negative change.
- Positive slopes increase from left to right on a graph, and indicate that a quantity or measure is becoming greater.
- Negative slopes decrease from left to right on a graph, and indicate that a quantity or measure is becoming less.
- Zero slopes are horizontal, and only the x-value changes.
- Undefined slopes are vertical,and only the y-value changes.
- To calculate the slope of a line you can use any two points on a line.
- To calculate the slope you find the vertical change from one point to the next on a line, and put that over the horizontal change. ie: rise/run.
