The midpoint of AB is M(-2, -1). If the coordinates of A are (-7, 2), what are the coordinates of B?

Coordinates of B is (3,-4)

Step-by-step explanation:

You multiply -2 by 2 to get -4 and then create the equation then you substitue -7 for +7 and add +7 to -4 which gives you 3 (x coordinate of B)

You multiply -1 by 2 to get -2 and then create the equation then you subtract 2 by -2 which gives you -4 (y coordinate of B)

To check your answer use the midpoint formula

  which will give you the midpoint (-2,-1)

step-by-step explanation:

is their an equation anywhere i can take a   look at it and see if i am right.
