Answer:
The coordinates of point B are (6,7).
Step-by-step explanation:
Given points are
Blue = A(-4,8)
Purple = M(1,7.5)
Green = B
It is given that point M is the midpoint of point A and B.
Let coordinates of points are (a,b).
Midpoint of two points is
Coordinates of midpoint are (1,7.5).
On comparing both sides we get
Therefore, the coordinates of point B are (6,7).
