Answer:
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
<em>Hence; the midpoint is (-1,-1)</em>
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
