Question

The midpoint of AB is M (0,6). If the coordinates of A are (2,5), what are the coordinates of B

Answer 1

(-2,7)

Explanation:

Use midpoint formula (x1+x2 divided by 2) (y1+y2 divided by 2)

Since you already have your midpoint then make an equation (point a+point b=point m)

solve for x coordinate

2+x divided by 2=0

multiply by 2

2+x=0

subtract 2

x=-2

Solve for y

5+y divided by 2=6

multiply by 2

5+y=12

subtract 5

y=7

(-2,7)
