Question

The midpoint of AB is M (-1,3). if the coordinates of A are (3,-2) what are the coordinates of B

Answer 1

(-5,8)

Explanation:

The x-coordinate difference between A and M is 3-(-1) which is 3+1=4. So you can subtract 4 from the M x-coordinate to get -5. You do the same to the y-coordinate. -2-3=-5. The difference is 5, so you would add 5 to the M y-coordinate to get 8. The final answer would be (-5,8).

Hope this helps! :)
