2. Section 13.1 and 13.5 Distance and Midpoint Formulas

3. The Question How do you find the distance and midpoint between two points?

4. Review  The coordinate plane

5. Review  Label the x and y axes

6. Review  Plot the following points on the coordinate plane:  (-3,4) (0,0) (1,-4) (-2,4) (-3,-2) (3,4) (3,-2) (2,-3) (-1,-4) (-2,-3)

7. Review

8. In general… Finding the distance between 2 points  Plot (x 1, y 1 ) and (x 2, y 2 )  What’s the distance between them?
