The midpoint of AB is M (-2,0) . If the coordinates of A are (1,-7), what are the coordinates of B

Step-by-step explanation:

Hope this helps u!!

B (- 5, 7 )

Step-by-step explanation:

Using the midpoint formula, then equate x and y coordinates

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

= - 2 ( multiply both sides by 2 )

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

x = - 5

= 0

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

y = 7

Coordinates of B = (- 5, 7 )

i dont know sorry
