1. Notes: Slope and Trend What is slope? How do you find the slope of a line?

2. slope The steepness of a line on a line graph.

3. 1. Pick any 2 points on a line. 2. Find the coordinates of each point (x,y). 3. Set up your data table. 4. Use the slope equation: slopey 2 - y 1 x 2 - x 1 X Y Point #1 Point #2 =

5. 1 2 0 2 2

6. 1 2 = 0 2 2

7. 1 2 = 0 2 2 Y 2 =

8. 1 2 = 0 2 2 Y 2 0 - =

9. 1 2 = 0 2 2 2 0 2 - =

10. 1 2 = 0 2 2 2 0 2 - = -

11. 1 2 = 0 2 2 2 0 2 - - = 2 4 =
