I have lab report attached below

I need help with the following:

A brief discussion of your conclusions, including how this experiment verifies (NOT 
PROVES) Ohm's Law.

I do not understand the difference between verifying something and proving it, im hoping someone can help me out.

Tech Brief
Objectives for the exercise
Use a multimeter to measure the resistance of two resistors and increasing voltages. From there,
we write down our findings. We then use these findings to create two graphs, measuring the
slope of the graphs to find the actual resistances.
Brief summary of the procedures
We first put together a circuit and connect it to a power supply to provide an electric current that
flows through the wire. We then put a 1K Q resistor in our circuit and used a multimeter to
measure the resistance going through the wire. From there, we increased the voltage running
through circuit and wrote down the voltages and related resistances running through the circuit.
We used the values to create graphs for the values, and after doing that we used the slopes to find
the true resistance of both resistors. We then put the true resistance in a table.
