When you finish…  You may no longer talk to your partner until everyone has finished  Take out your warm up sheet  In today’s box: reflect on the quiz  How do you think you did?  What could you have done differently when taking notes in class?

Section 13.1 and 13.5 Distance and Midpoint Formulas

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

Review  The coordinate plane

Review  Label the x and y axes

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)

Review

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