Question

The midpoint of uv is (5, –11). The coordinates of one endpoint are U(3, 5). Find the coordinates of endpoint V.

Answer 1

Work backwards from the midpoint formula.
M(5, -11) = ((5 + x_2)/2, (-11 + y_2)/2)

Answer 2

for the points (x1,y1) and (x2,y2)
the coordinates of the midpoint are\[(\frac{x1+x2}{2}, \frac{y1+y2}{2})\]so u in ur question the midpoint is (5,-11)
\[(5,-11)=(\frac{3+x2}{2}, \frac{5+y2}{2})\]
now for the x coordinate of V\[5=\frac{3+x2}{2}\]solve for x2

and for the y coordiante of V\[-11=\frac{5+y2}{2}\]solve for y2

Answer 3
