We can see from the graph that as the current increases the voltage also increases.
This agrees with our prediction.
In fact, since the line of best fit is a straight line through the origin, we can be even more precise.
We can say that the voltage across the wire is directly proportional to the current flowing through it.
As the voltage increases the current increases in direct proportion.
This means that if you double the voltage the current doubles, if you triple the voltage, the current triples, if you halve the voltage, the current halves, and so on.
