Hope this Helps :)
We know that AB is a perpendicular bisector of IK.
Therefore point J is the midpoint of IK.
AJ = BJ Could be but based on the given information we cannot conclude it.
IJ = IK True.
A is the midpoint of IK. Wrong. J is the midpoint of IK.
Answer:
IJ = IK
The slope would be undefined, because it would be going straight vertical.
