Using the midpoint formula,


(x1 + x2)/(2) = 4 \\ (x1 + 2)/(2) = 4 \\ x1 + 2 = 4 * 2 \\ x1 + 2 = 8 \\ x1 = 8 - 2 \\ x1 = 6


(y1 + y2)/(2) = 4 \\ (y1 + 1)/(2) = 4 \\ y1 + 1 = 4 * 2 \\ y1 + 1 = 8 \\ y1 = 8 - 1 \\ y1 = 7

Therefore,

Coordinates of B are (6 , 7)

Answer:

(6,7)

Explanation:

let the co-ordinates of B are (x,y)

then
(2+x)/(2) =4\\2+x=8\\x=8-2=6\\(1+y)/(2) =4\\1+y=8\\y=8-1=7\\

so B is (6,7)
