The midpoint of AB is at (−3,4). If A=(6,−3), find B.

Step 1

The coordinates are ordered pairs with the x value listed first.

The change in the x position is 6−(−3)=9

The change in the y position is -3−4=-7

Step 2

Since the midpoint is halfway between A and B, the change will stay the same.

Therefore,

x is −3−9=−12

and

y is 4−(-7)=11
