One endpoint of a line segment is (4,3) and its midpoint is (2,9). What is the sum of the coordinates of the other endpoint?

We have this

 

( 4  + x) / 2  =  2                (3 + y) / 2  = 9

 4 + x  =  4                          3 + y  =  18

x = 0                                   y =  15

 

So...the other endpoint is  (0,15)  and the sum of its coordinates is  15
