Geometry help: Point A is located at (1,5), and point M is located at (-1,6). If point M is the midpoint of AB. Find the location of point B. (-3,7) (0, 5.5) (3,4) (0,5)

Answer 1

midpoint of (x1,y1) and (x2,y2) = [(x1 + x2)/2, (y1 + y2)/2]

here (x1,y1) = (1,5) and (x2,y2) = (-1,6)

so using formula [(1 + -1)/2, (5 + 6)/) = (0.5.5)
