Slope of Kinetic vs Potential(Spring)

[youknow789]

Homework Statement

Been trying the last few hours to figure out what the slope of a kinetic vs potential graph means. I did a lab this past week dealing with springs and a glider. Was asked to graph a X^2max-x^2 vs v^2 graph. Made the graph but have no idea what the slope means.

Homework Equations

The Attempt at a Solution

Solved for total mechanical energy and change in potential energy and still do not know what slope means. Maybe I put them on the wrong x-y axis. Right now I have v^2 on the y axis. Can somebody please point me in the right direction.

not sure if it helps but here is a previous question I asked about same lab. https://www.physicsforums.com/showthread.php?p=3562578
