Answer

$\boxed{(16.0, 23.0)}$ is the coordinates of the midpoint of line CD.

Steps

Step 1 ：Given point C has coordinates $(22, 18)$ and point D has coordinates $(10, 28)$.

Step 2 ：To find the midpoint of line CD, we need to find the average of the x-coordinates and the average of the y-coordinates of points C and D.

Step 3 ：Midpoint_x = $\frac{22 + 10}{2} = 16.0$

Step 4 ：Midpoint_y = $\frac{18 + 28}{2} = 23.0$

Step 5 ：$\boxed{(16.0, 23.0)}$ is the coordinates of the midpoint of line CD.
