8) Find the endpoint Cif M is the midpoint of segment CD and M (2, 4) and D (5,7) a) (-3,-3) b) (-2,-1) c) (-1,1) d) (2,4)

8. c. (-1, -1)

9. a. (-6, -1)

b. True

Step-by-step Explanation:

8. Given the midpoint M(2, 4), and one endpoint D(5, 7) of segment CD, the coordinate pair of the other endpoint C, can be calculated as follows:

let

Rewrite the equation to find the coordinates of C

and

Solve for each:

Coordinates of endpoint C is (-1, 1)

9. a.Given segment AB, with midpoint M(-4, -5), and endpoint A(-2, -9), find endpoint B as follows:

let

and

Solve for each:

Coordinates of endpoint B is (-6, -1)

b. The midpoint of a segment, is the middle of the segment. It divides the segment into two equal parts. The answer is TRUE.
