Question

The midpoint of AB is M (0,4) . If the coordinates of A are (8,7) ,

what are the coordinates of B?

Answer 1

(-7,0)

Explanation:

If you start from (0,4) getting to (8,7) means going right 4 times and up 7 times. that means that to get to B, you must go left 4 times and down 7 times. All of this makes more sense if you look at a graph.
