From the above graph,It is seen  that the voltage increases twice with the increase in current.

Explanation:

Observing the above provided graph,It is clearly understood that,

It is linear If one quantity(Current) increases, the other one(Voltage) also increases.There is a direct relationship between voltage and current.By observing the graph clearly, we can see that there is an increase in 1 Ampere of current when there is an increase in power supply of 2 volts.By considering all the above noticed observation it is clearly known that the voltage is increased twice the amount of increase in current.

Yes i think so not 100 percent sure though
