                                        Distance Formula
Example 1:
Find the distance between the points A  2,3 and
B  6,7 




Example 2:
Find the distance between the points M  2, 4 and
N  3, 7 




How do you find the vertical distance between two points?



How do you find the horizontal distance between two points?
Distance Formula
                                                                            A
Consider the points A  xA , yA  and B  xB , yB 

What is the horizontal distance between the points?


What is the vertical distance between the points?

Thus the distance between points A and B is:                         B



                d     xA  xB    y A  yB 
                                2                  2




Example 3: Find the distance between the points P  0,0 and Q  2, 7 




Example 4: Find the distance between the points A  7,3 and B  6, 5
