Answer: B = (-1, 0)
Step-by-step explanation:
Given: M = (-3, 2) A = (-5, -4)
[tex]M_x=\dfrac{A_x+B_x}{2}\qquad \qquad \qquad M_y=\dfrac{A_y+B_y}{2}\\\\\\-3=\dfrac{-5+B_x}{2}\qquad \qquad \qquad 2=\dfrac{-4+B_y}{2}\\\\\\-6=-5+B_x\qquad \qquad \qquad 4=-4+B_y\\\\\\-1=B_x\qquad \qquad \qquad \qquad 0=B_y[/tex]
