Since, the coordinates of the midpoint of line RS are M.
The coordinates of endpoint R are (-2,10)
We have to determine the coordinates of endpoint S.
The midpoint of the line segment joining the points and
is given by the formula
.
Here, The endpoint R is (-2,10) So,
Let the endpoint S be
The midpoint coordinate M is .
So,
Now,
So, the other endpoint S is (8,0).
