Part A: Plot the points A(-8,7) and B(6,-9). Mark the halfway point on AB and label it point M. What are the coordinates of M? Part B: Plot point C(2,7). If M is the midpoint of CD, what are the coordinates of D? please help me

a.

b.

Step-by-step explanation:

Given

A(-8,7) and B(6,-9).

Solving (a):

Determine the Midpoint M;

This is calculated as follows;

Where

Substitute these values in the formula

Hence; the midpoint is (-1,-1)

Solving (a):

Here, we have

C = (2,7)

M; Midpoint = (-1,-1)

Required: Determine D

This is calculated as follows;

Where

Substitute these values in the formula

Solving for x2

Multiply both sides by 2

Subtract 2 from both sides

Solving for y2

Multiply both sides by 2

Subtract 7 from both sides

Hence, the coordinates of D is

it would be 6xy and -16xy.
