Question

the midpoint of uv is (5 -11) the concordance of one endpoint are u(3,5) find the coordinates of endpoint v

Answer 1

the midpoint has coordinates (x,y) that are the average of the endpoints. So,

(3+x)/2 = 5
(5+y)/2 = -11

Or, you can reason that 5 2 larger than 3, so the x-coordinate of v will be another 2 larger. Same for y.
