The coordinates of other endpoint S is (3, 2)
<h3><u>Solution:</u></h3>
Given that midpoint of RS is M
Given endpoint R(23, 14) and midpoint M(13, 8)
To find: coordinates of the other endpoint S
<em><u>The formula for midpoint is given as:</u></em>
For a line containing containing two points
and
midpoint is given as:

Here in this problem,
m(x, y) = (13, 8)

Substituting the given values in above formula, we get

Comparing both the sides we get,

Thus the coordinates of other endpoint S is (3, 2)
