The document defines slope and explains how to calculate it using the rise over run formula. It provides two examples of computing slope, one using a graph and another using two coordinate points. The slope formula is defined and examples are worked through, with the second example calculating the slope of the line passing through points (-3, -5) and (2, 1).

Slope of Lines
- 1. Slope of Lines • Learning Objective • Define the slope formula of the line • Compute values of slope using two examples
- 2. Slope
- 3. Rise and Run • The rise can be positive or negative • A positive rise corresponds to a vertical change up • A negative rise corresponds to a vertical change down • The run can be positive or negative • A positive run corresponds to a horizontal change right • A negative run corresponds to a horizontal change left
