The midpoint of AB is M(1, 3). If the coordinates of A are(4,1), what are the coordinates of B?

Oxana [17]

Answer:

B(-2,5)

Step-by-step explanation:

$\frac{x + 4}{2} = 1 \\ 2 \times \frac{x + 4}{2} = 1 \times 2 \\ x + 4 = 2 \\ x = 2 - 4 \\ x = - 2 \\ \frac{y + 1}{2} = 3 \\ 2 \times \frac{y + 1}{2} = 3 \times 2 \\ y + 1 = 6 \\ y = 6 - 1 \\ y = 5$

Hope that this is helpful.

Have a nice day.
