Weird keyframe graph

[DualSaga184]

I'm trying to do a simple position movement from one point to the other with a linear line.

I've done this plenty before and yet when I did it this time it didn't give me a linear curve, but rather this:

I'm not sure why it's doing this, because I have no additional keyframes between the two points, so it should default to linear right?

I'd appreciate some help with this issue.

Spatial keyframes default to auto-bezier, which can produce the types of graphs you see. Drag to select both keyframes in the graph editor then right-click on one of the  keyframes, choose Keyframe Interpolation, then change the Spatial Interpolation value to Linear.

Thank you, that was exactly it.
