Question

The midpoint of AB is M (0, –1). If the coordinates of A are (4, 3), what are the

coordinates of B?

Answer 1

B=(-4,-5)

Explanation:

Use midpoint formula but set as an equation

Use (x,y) as point B and use M points to set equal to

4+x divided by 2= 0

Multiply by 2

4+x=0

Subtract 4

x=-4

Now do the y

3+y divided by 2=-1

Multiply by 2

3+y=-2

Subtract 3

y=-5

Hope this helped!
