Calculating the Hall Coefficient for a sample of germanium

Hey everyone! This is my first time posting here, so my apologies if I'm doing things wrong...which I probably am.
So for my modern physics lab report, we're investigating the Hall effect. We measured Hall voltages as we adjusted a DC current source. The first question in my manual is to calculate the Hall coefficient using my data along with information they gave me for the sample. Here's the equation they gave us for the Hall coefficient:
RH=(VH * w)/(BI)
where RH is the coefficent, VH is the Hall voltage, w is the width of the sample, B is the magnetic field, and I is the current applied. They've given me the width of the sample and we held B to be constant (I recorded the value of it in my lab notebook).
The problem is that I have a table of data for Hall voltage vs current (10 measurements), so how am I supposed to calculate just one coefficient for the sample when I have a bunch of different recorded values for the Hall voltage and the current? I'm super confused right now.
Hopefully my question makes sense - let me know if it doesn't and I'll do my best to clarify!

You plot the Hall voltage as a function of current, then fit it with a linear function. The relevant result is the slope.

Yup, I figured it out! :) Thanks for answering.
