You have to label it but try 1 and 1/4, -1 and 1/4,2, and -2
The First One
The Third One

The others result in a lower number than what they are supposed to be. The 3 correct ones end with the exact number of the equations solution number.
The distance between B and B' will be the same as distance between A and A'.
= sqrt ( (5-1)^2 + ( 1 - -2)^2)
= sqrt (16 + 9)
= 5 units answer
