U(2, 5 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ (x₁ + x₂ ) , (y₁ + y₂ ) ]

let U = (x, y)

Use the midpoint formula and equate to the coordinates of M , that is

x = (x + 17) = 9.5 ( multiply both sides by 2 )

x + 17 = 19 ( subtract 17 from both sides )

x = 2

y = (y - 11 ) = - 3 ( multiply both sides by 2 )

y - 11 = - 6 ( add 11 to both sides )

y = 5

Thus coordinates of U = (2, 5 )
