Using the midpoint formula, the coordinates of Q are: <em>A. (-10, 1)</em>
<h3>What is the Midpoint Formula?</h3>- Midpoint formula is given as,
Thus, given that:
- M is the midpoint of PQ.
- M (-4, 7)
- P (2, 13).
Therefore:
Solve for x-coordinate of P:
-4 = 1/2(2 + x1)
2(-4) = 2 + x1
-8 = 2 + x1
-8 - 2 = x1
x1 = -10
Solve for y-coordinate of P:
7 = 1/2(13 + y1)
14 = 13 + y1
y1 = 1
Therefore, using the midpoint formula, the coordinates of Q are: <em>A. (-10, 1)</em>
