Answer 1

need x_v and y_v

the line UV is a hypotenuse of a right triangle

one leg parallel to x-axis and other leg parallel to y-axis

told midpoint of hypotenuse is (5,-11) and x_u=3,,,y_u=5

then (x_u+x_v)/2=5 ,,,,,,(midpoint formula on number line)

x_v=7

and (y_u+y_v)/2=-11

y_v=-27

Answer 2

V(7,-27) 3 to 5 = 2, 5 to 7 = 2, -11 to 5 = 16, -27 to -11 = 16
