The midpoint of AB is at 24 If A58 find B The midpoint of AB

The midpoint of AB is at (2,4). If A=(5,8), find B.

The midpoint of AB is at (3,3). If A=(-9,0), find B.

If two points A (x1, y1) and B (x2, y2) is given:

Midpoint is given by : ( x1+x2)/2 , (y1+y2)/2

midpoint of AB is at (2,4). If A=(5,8), find B

So, -2 = (5+x2)/2

x2 = -9

4 = ( -8 +y2)/2

y2 = 16

B ( -9, 16)

midpoint of AB is at (3,3). If A=(-9,0), find B

-3 = (x2 -9)/2

x2 = 3

3 = (y2 +0)/2

y2 = 6

B ( 3, 6)
