Answer: B = ( -3 , 2)

Step-by-step explanation:

You would use a mid point formular because you are trying to find the middle of a line . The midpoint formular is (X1 + X2 , Y1 + Y2 )  

                                                                 /2            /2

From the information given A is (7 , -2 )

If you fill it in it would be 7 + X , -2 + X

                                         /2         /2           =   (2 , 0 )

The only posible solution would be 7- 3 /2  , -2 + 2 / 2

Makeing B (-3, 2).

You would multiply this just like any other multiplication question. 
There is some work of course, but I'm not going to write it out here...
You are going to end up with -15.41, which is already rounded to the nearest hundredth.

Hope this helped :)
