Point F on the coordinate grid is reflected across a line to create point F’. Then, points E, F, and F’ I connected to create a triangle. kari says Point E must be on the perpendicular bisector of the line FF’, regardless of the line across which point F was reflected. Part #1:
enter a equation of a line across which F could be reflected to support Kari claim

Part #2
enter the equation of a line across which F could be reflected a show that kari’s claim is incorrect.
