2. Distance Formula

3. Example
Determine the distance between points A (-1, 4) and B (2, 7).

4. Slope “Rise” can be either positive or negative.
“Run” is ALWAYS positive.

5. Example
Determine the slope of the line connecting the points (-2, 1) and (5, -10).

6. Example 2
Determine the slope of the line connecting the points (512, -20) and (-600, -125).

7. Linear Equations Linear equations have a degree of 1.
The degree of a polynomial equation is the highest power on the independent variable.
Examples:

8. Slope-Intercept Form The slope-intercept form of a line is:
Example: Determine the equation of a line passing through the point (3, 4) and having a slope of 6.
