Point A is at (-2,-7) and point M is at (2.5, -1.5). MY
Point M is the midpoint of point A and point B.
What are the coordinates of point B?

B(7 , 4)

Step-by-step explanation:

(x₁ , y₁) = A(-2 , -7)

(x₂ , y₂) = Point B

Midpoint(5.5, -1.5)

Compare x-coordinates  & y-coordinates

-2+ x₂ = 2.5*2     ; -7+ y₂ = -1.5*2

-2+ x₂ = 5            ; -7 +y₂ = -3

    x₂ = 5 +2       ;        y₂ = -3 + 7

    x₂  = 7            ;        y₂ = 4

B(7 , 4)

560
