Chapter 8.3, Problem 15E

To determine

The coordinates of the point M.

Answer to Problem 15E

  $\left(5,2\right)$

Explanation of Solution

Given:

The given points are:

  $\begin{array}{l}C\left(3,-5\right)\\ D\left(7,9\right)\end{array}$

Calculation:

The coordinates of midpoint will be:

  $\begin{array}{l}=\left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\right)\\ =\left(\frac{3+7}{2},\frac{-5+9}{2}\right)\\ =\left(5,2\right)\end{array}$
