1. Introduction To Slope

2. Slope is a measure of Steepness.

3. Types of Slope Positive Negative slope of zero undefined

4. Slope is sometimes referred to as the “Rate of Change”.

5. Slope is represented by the letter “m” Why? I have no idea so I just think m for mountains and mountains have slope.

6. Slope may sometimes be written as m =∆y. ∆x What is ∆ ? The Greek letter Delta which means “the change in”

7. If given the graph of a line, find the slope by using the “triangle” method to find the change in y OVER the change in x

8. Change in y = 4 Change in x = 5 m= the change in y the change in x m=

9. Try These

10. And These

11. To Review: Create two points on the line where two grid lines meet Start with the point on the left Draw a vertical line until you are even with the second point Then draw a horizontal line to the second point Put the change in y-values over the change in x-values Reduce the fraction

12. The End
