5. Mis the midpoint of CD. C has coordinates (-1,-1) and M has coordinates (3,5). Find the coordinates of D.

Answer/Step-by-step Explanation:

4. Midpoint (M) of AB, for A(-2, -3) and B(1, 2) is given as:

Let

Thus:

5. Given M(3, 5) as midpoint of CD, and C(-1, -1),

let

Rewrite the equation to find the coordinates of D

and

Solve for each:

Coordinates of D is (7, 11)

is this part of a question or something

the answer is 13 cm
