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
