What Does the Slope Represent in a Voltage vs. Distance Graph?

[LadiesMan]

Well I have this lab on electric field lab and what I did was measure the voltage from different distances on a parallel plate. So when I plotted the graph Voltae vs. Distance, I got a linear line and the equation was y = 85x (somewhat like that disregarding the y-intercept). My concern is what does the constant/slope represent? I'm really stumpped. Thanks

2. y = 85x



3. I think it is the electric field strength or electric potential?

A graph of V against d...
the gradient would be V/d which is the definition of electric field strength for parallel plates

yea e = v/r . V/r is the slope of your graph, 85.
