Answer:
B= (-7, -5)
Step-by-step explanation:
The midpoint point formula is (X1 plus X2) divided by 2 to get the x value of the midpoint and do the same for the Y value, ( Y1 plus Y2) divided by 2. So, because you already have the midpoint you have to work backwards. So for the x value of B the formula would be (-5 + X) divided by 2 equals -6 and then you just solve for X. Same thing for the Y value (7 + Y) divided by 2 equals 1. Then you should get both values for B (-7, -5)
