Answer:
The answer is
[tex]( \frac{3}{2}  \:  ,  \frac{5}{2} ) \:  \: or \:  \: (1.5 \:  \:  ,  \:  \: 2.5)[/tex]
Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
[tex]M = ( \frac{x1 + x2}{2} \:   , \:  \frac{y1 + y2}{2} )[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
C (4,6) and D(-1, -1)
The coordinates of the midpoint is
[tex]M = ( \frac{4 - 1}{2}  ,  \:  \frac{6 - 1}{2} )[/tex]
We have the final answer as
[tex]( \frac{3}{2}  \:  ,  \frac{5}{2} ) \:  \: or \:  \: (1.5 \:  \:  ,  \:  \: 2.5)[/tex]
