To determine if the value of variable
Given:
From the midpoint
-
For the
-coordinates: -
For the
-coordinates:
Now, let's solve these equations:
For the -coordinates:
Multiply both sides by
For the -coordinates:
Multiply both sides by
We now have a system of equations:
To solve this system for
Now substitute
Since we found
Conclusion:
So the correct choice is:
A. To determine the value of
