Question

PQ has a midpoint of M. the coordinates of M are (-4, 7) and the coordinates of P are (2, 13). What are the coordinates of Q?

Answer 1

Using the midpoint formula, the coordinates of Q are: A. (-10, 1)

What is the Midpoint Formula?

• Midpoint formula is given as, $M(x, y) = (\frac{x_2 + x_1}{2} , \frac{y_2 + y_1}{2})$

Thus, given that:

• M is the midpoint of PQ.
• M (-4, 7)
• P (2, 13).

Therefore:

$M(-4, 7) = (\frac{2 + x_1}{2} , \frac{13 + y_1}{2})$

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: A. (-10, 1)
