<u>ANSWER:</u>
The midpoint of AB is M(-5,1). The coordinates of B are (-6, 7)
<u>SOLUTION:
</u>
Given, the midpoint of AB is M(-5,1).  
The coordinates of A are (-4,-5),  
We need to find the coordinates of B.
We know that, mid-point formula for two points A and B
 and B  is given by
 is given by

Here, in our problem, 
Now, on substituting values in midpoint formula, we get

On comparing, with the formula,



Hence, the coordinates of b are (-6, 7).
