1. Slopes

2. Formulas Slope= rise/run Change of y/change of x

3. Lattice Point When finding the slope from an origin you can use the lattice point.

4. Triangle The triangle method is another method used to find the slope.

6. Question: Extra Credit!!

9. Example

10. First Way You can find the slope in Three Ways that we learned. 1st way: Rise/run Count the rise Yes, it is 2 Count the run Yes, it is -8 We have 2/-8 when reduced it is - 1/4

11. Second Way: Lattice Point We see that the line crosses at (4,-2) and (-6,-2). Remember: We can use the lattice points when the line does not cross the origin.

12. Third Way: Triangle Use the two lattice points you have. Connect them by forming a triangle.

13. Challenge: Is this a positive slope or a negative slope?Why?

14. Challenge: What is the slope?
