The midpoint of AB is M(5, -5). If the coordinates of A are (3, -6), what are the coordinates of B?

(7,-4)

Step-by-step explanation:

let b be x2,y2

then apply mid point formula

x=(x1+x2)/2

y=(y1+y2)/2

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

the answer is  

a.
