  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.

  5. Question: Extra Credit!!

  6. Question: Extra Credit!!

  7. Question: Extra Credit!!

  8. Example

  9. 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

  10. 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.

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

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

  13. Challenge: • What is the slope?
