Answer:
M(5,2)
Step-by-step explanation:
We use the midpoint rule:
[tex]( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} )[/tex]
We just have to find the arithmetic mean of the x and y-coordinates.
The endpoints of CD are given as C(3,−5) and D(7, 9).
We substitute these values to get:
[tex]( \frac{7 + 3}{2}, \frac{9 + - 5}{2} )[/tex]
[tex]( \frac{10}{2}, \frac{4}{2} )[/tex]
[tex](5, 2)[/tex]
Therefore the coordinates of the midpoint M of CD are (5,2)
