The midpoint of CD is M=(1, 2). One endpoint is C = (6, -2). Find the coordinates of the other endpoint, D.

Endpoint = (-4,6)

Step-by-step explanation:

To find any endpoint use the formula    

multiply each by 2  to simplify

    take the equations and simplify

6+ = 2                          -2+ = 4  =  

-6       -6                          +2       +2

    = -4                               =  6

To check use the Midpoint formula

42
