Point A is at (-2, -7) and point M is at (2.5, -1.5).
Point M is the midpoint of point A and point B.
What are the coordinates of point B?
9-
8

(.25,-1.5)

Step-by-step explanation:

the formula is x coordinate= (x1-x2)/2 y coordinate= (y1-y2)/2

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y
