Lesson 9.5 The Distance Formula Objective: After studying this section, you will be able to use the distance formula to compute lengths of segments in the coordinate plane
Theorem If P = (x1, y1) and Q = ( x2,y2) are any two points, then the distance between them can be found with the formula
Example 1 If A = (2, 3) and B = (7, 15), find AB Example 2 If D = (7, 1), E = (9, -5), and F = (6, -4), find the length of the median from F to DE D M F E
