Answer: B = ( -3 , 2)

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).
