Answer:

B (- 5, 7 )

Explanation:

Using the midpoint formula, then equate x and y coordinates

let coordinates of B = (x, y ) , then


(x+1)/(2) = - 2 ( multiply both sides by 2 )

x + 1 = - 4 ( subtract 1 from both sides )

x = - 5


(y-7)/(2) = 0

y - 7 = 0 ( add 7 to both sides )

y = 7

Coordinates of B = (- 5, 7 )
